Volume Problem Solving - Basic
Volume - problem solving - intermediate, volume problem solving - advanced.
This section revolves around the basic understanding of volume and using the formulas for finding the volume. A couple of examples are followed by several problems to try.
Find the volume of a cube of side length \(10\text{ cm}\). \[\begin{align} (\text {Volume of a cube}) & = {(\text {Side length}})^{3}\\ & = {10}^{3}\\ & = 1000 ~\big(\text{cm}^{3}\big).\ _\square \end{align}\]
Find the volume of a cuboid of length \(10\text{ cm}\), breadth \(8\text{ cm}\). and height \(6\text{ cm}\). \[\begin{align} (\text {Area of a cuboid}) & = l × b × h\\ & = 10 × 8 × 6\\ & = 480 ~\big(\text{cm}^{3}\big).\ _\square \end{align}\]
I made a large ice cream cone of a composite shape of a cone and a hemisphere. If the height of the cone is 10 and the diameter of both the cone and the hemisphere is 6, what is the volume of this ice cream cone? The volume of the composite figure is the sum of the volume of the cone and the volume of the hemisphere. Recall the formulas for the following two volumes: \( V_{\text{cone}} = \frac13 \pi r^2 h\) and \( V_{\text{sphere}} =\frac43 \pi r^3 \). Since the volume of a hemisphere is half the volume of a a sphere of the same radius, the total volume for this problem is \[\frac13 \pi r^2 h + \frac12 \cdot \frac43 \pi r^3. \] With height \(h =10\), and diameter \(d = 6\) or radius \(r = \frac d2 = 3 \), the total volume is \(48\pi. \ _\square \)
Find the volume of a cone having slant height \(17\text{ cm}\) and radius of the base \(15\text{ cm}\). Let \(h\) denote the height of the cone, then \[\begin{align} (\text{slant height}) &=\sqrt {h^2 + r^2}\\ 17&= \sqrt {h^2 + 15^2}\\ 289&= h^2 + 225\\ h^2&=64\\ h& = 8. \end{align}\] Since the formula for the volume of a cone is \(\dfrac {1}{3} ×\pi ×r^2×h\), the volume of the cone is \[ \frac {1}{3}×3.14× 225 × 8= 1884 ~\big(\text{cm}^{2}\big). \ _\square\]
Find the volume of the following figure which depicts a cone and an hemisphere, up to \(2\) decimal places. In this figure, the shape of the base of the cone is circular and the whole flat part of the hemisphere exactly coincides with the base of the cone (in other words, the base of the cone and the flat part of the hemisphere are the same). Use \(\pi=\frac{22}{7}.\) \[\begin{align} (\text{Volume of cone}) & = \dfrac {1}{3} \pi r^2 h\\ & = \dfrac {1 × 22 × 36 × 8}{3 × 7}\\ & = \dfrac {6336}{21} = 301.71 \\\\ (\text{Volume of hemisphere}) & = \dfrac {2}{3} \pi r^3\\ & = \dfrac {2 × 22 × 216}{3 × 7}\\ & = \dfrac {9504}{21} = 452.57 \\\\ (\text{Total volume of figure}) & = (301.71 + 452.57) \\ & = 754.28.\ _\square \end{align} \]

\[\text{ I. A full cylindrical bar } \hspace{.4cm} \text{ or } \hspace{.45cm} \text{ II. A ball plus a cone }\]
How many cubes measuring 2 units on one side must be added to a cube measuring 8 units on one side to form a cube measuring 12 units on one side?
This section involves a deeper understanding of volume and the formulas to find the volume. Here are a couple of worked out examples followed by several "Try It Yourself" problems:
\(12\) spheres of the same size are made from melting a solid cylinder of \(16\text{ cm}\) diameter and \(2\text{ cm}\) height. Find the diameter of each sphere. Use \(\pi=\frac{22}{7}.\) The volume of the cylinder is \[\pi× r^2 × h = \frac {22×8^2×2}{7}= \frac {2816}{7}.\] Let the radius of each sphere be \(r\text{ cm}.\) Then the volume of each sphere in \(\text{cm}^3\) is \[\dfrac {4×22×r^3}{3×7} = \dfrac{88×r^3}{21}.\] Since the number of spheres is \(\frac {\text{Volume of cylinder}}{\text {Volume of 1 sphere}},\) \[\begin{align} 12 &= \dfrac{2816×21}{7×88×r^3}\\ &= \dfrac {96}{r^3}\\ r^3 &= \dfrac {96}{12}\\ &= 8\\ \Rightarrow r &= 2. \end{align}\] Therefore, the diameter of each sphere is \[2\times r = 2\times 2 = 4 ~(\text{cm}). \ _\square\]
Find the volume of a hemispherical shell whose outer radius is \(7\text{ cm}\) and inner radius is \(3\text{ cm}\), up to \(2\) decimal places. We have \[\begin{align} (\text {Volume of inner hemisphere}) & = \dfrac{1}{2} × \dfrac{4}{3} × \pi × R^3\\ & = \dfrac {1 × 4 × 22 × 27}{2 × 3 × 7}\\ & = \dfrac {396}{7}\\ & = 56.57 ~\big(\text{cm}^{3}\big) \\\\ (\text {Volume of outer hemisphere}) & = \dfrac{1}{2} × \dfrac{4}{3} × \pi × r^3\\ & = \dfrac {1 × 4 × 22 × 343}{2 × 3 × 7}\\ & = \dfrac {2156}{7}\\ & = 718.66 ~\big(\text{cm}^{3}\big) \\\\ (\text{Volume of hemispherical shell}) & = (\text{V. of outer hemisphere}) - (\text{V. of inner hemisphere})\\ & = 718.66 - 56.57 \\ & = 662.09 ~\big(\text{cm}^{3}\big).\ _\square \end{align}\]
A student did an experiment using a cone, a sphere, and a cylinder each having the same radius and height. He started with the cylinder full of liquid and then poured it into the cone until the cone was full. Then, he began pouring the remaining liquid from the cylinder into the sphere. What was the result which he observed?
There are two identical right circular cones each of height \(2\text{ cm}.\) They are placed vertically, with their apex pointing downwards, and one cone is vertically above the other. At the start, the upper cone is full of water and the lower cone is empty.

Volume Questions
Volume questions and answers are available in an easily understandable format along with required formulas. Students can practise questions on finding the volume of various solids provided here, and verify their solutions with the available answers. This is the best way to learn about various problem-solving techniques of solids in geometry.
What is volume?
Volume is the amount of space occupied by a solid shape in a three-dimensional plane or region. Some examples of solids include cubes, cuboids, spheres, cones, cylinders, etc.
- Volume of cube = a 3 , where a is the edge of the cube.
- Volume of cuboid = lbh, where l = length, b = breadth and h = height.
- Volume of sphere = (4/3) πr 3 , where r is the radius of the sphere.
- Volume of cylinder = πr 2 h, where r is the radius of the circular bases and h is the height.
- Volume of cone = (⅓) πr 2 h, where r is the radius of the circular base and h is the height.
- Volume of hemisphere = (2/3) πr 3 , where r is the radius of the sphere.
- Volume of frustum = πh/3 (R 2 + r 2 + Rr), where ‘R’ and ‘r’ are the radii of the base and top of the frustum.
- Volume of prism = Base Area x Height.
- Volume of pyramid = ⅓ (Area of base) (Height).

Volume Questions and Answers
1. Find the volume of a cuboidal box with dimensions 11 cm × 8 cm × 13 cm.
Given, the dimensions of a cuboidal box: 11 cm × 8 cm × 13 cm
Length = l = 11 cm
Breadth = b = 8 cm
Height = h = 13 cm
As we know, volume of a cuboid = lbh
= 11 × 8 × 13
Thus, the volume of the cuboidal box is 1144 cm 3 .
2. What is the volume of a sphere of diameter 21 units?
Diameter of the sphere = 21 units
Radius of the sphere = (21/2) units
Volume of a sphere = (4/3) πr 3
= (4/3) × (22/7) × (21/2) × (21/2) × (21/2)
Therefore, the volume of the sphere is 4851 cubic units.
3. A cuboidal block of wood was cut into eight equal cubes of edges 4 cm. Find the volume of the initial block of wood.
Edge of a cubical wood = 4 cm
Volume of the cube = a 3
= 4 × 4 × 4
Volume of 8 such cubes = 8 volume of one cube
Hence, the volume of the initial cuboidal block of wood is 512 cm 3 .
4. If three solid spherical beads of radii 3 cm, 4 cm, and 5 cm, respectively, are melted into one spherical bead, then find its radius in cm.
Radii of three solid spherical beads: 3 cm, 4 cm and 5 cm
As we know, the volume of a sphere = (4/3) πr 3
Let R be the radius of the new spherical bead, which is made by melting three spherical beads.
Volume of a new spherical bead = Sum of volumes of three spherical beads
(4/3)πR 3 = (4/3) × 3 × 3 × 3 + (4/3) × 4 × 4 × 4 + (4/3) × 5 × 5 × 5
(4/3)πR 3 = (4/3)π (27 + 64 + 125)
Hence, the radius of the spherical bead is 6 cm.
5. How many bricks, each measuring 25 cm x 11.25 cm x 6 cm, will be needed to build a wall of 8 m x 6 m x 22.5 cm?
Dimensions of a brick = 25 cm x 11.25 cm x 6 cm
Dimensions of a wall = 8 m x 6 m x 22.5 cm
= 800 cm x 600 cm x 22.5 cm
Number of bricks = volume of the wall/ volume of a brick
= (800 x 600 x 22.5) / (25 x 11.25 x 6)
6. Find the depth of the cylindrical tank if its capacity is 1848 m 3 and the diameter of the base is 14 m.
Let h be the depth of the cylindrical tank.
Diameter of the base = 14 m
Radius of the circular base = r = 14/2 = 7 m
Volume of the cylindrical tank = πr2h
So, πr 2 h = 1848 m 3
(22/7) × 7 × 7 × h = 1848
h = 1848/(22 × 7)
Therefore, the depth of the cylindrical tank is 12 m.
7. What is the ratio of the volume of a cone, a sphere and a cylinder if each has the same radius and height?
Let r be the radius of the cone, sphere and cylinder.
Let h be the height of the cone and cylinder.
Also, r = h
We know that,
Volume of cone = (1/3)πr 2 h = (1/3)πr 3
Volume of sphere = (4/3)πr 3
Volume of cylinder = πr 2 h = πr 3
Volume of cone : Volume of sphere : Volume of cylinder
= (1/3)πr 2 h : (4/3)πr 3 : πr 2 h
= (1/3)πr 3 : (4/3)πr 3 : πr 3
= (1/3) : (4/3) : 1
= 1 : 4 : 3
Therefore, the required ratio is 1 : 4 : 3.
8. Find the water weight in a conical vessel that is 21 cm deep and 16 cm in diameter.
Depth of height of a conical vessel = h = 21 cm
Diameter of the circular base = 16 cm
Radius = r = 16/2 = 8 cm
Volume of a cone = (1/3)πr 2 h
= (1/3) × (22/7) × 8 × 8 × 21
= 1408 cm 3
= (1408/1000) kg
Therefore, the weight of the water in a conical vessel is 1.408 kg.
9. A vessel is in the form of a frustum of a cone. Its radius at one end and the heights are 8 cm and 14 cm, respectively. If its volume is 5676/3 cm 3 , find the radius at the other end.
Radius of one circular end = r 1 = 8 cm
Height of the frustum = h = 14 cm
Let r2 be the radius of the other circular end.
Volume of the frustum = πh/3 (r 1 2 + r 2 2 + r 1 r 2 )
= (1/3) × (22/7) × 14 × [(8) 2 + (r 2 ) 2 + 8r 2 ]
According to the given,
(1/3) × (22/7) × 14 × [(8) 2 + (r 2 ) 2 + 8r 2 ] = 5676/3 cm3
64 + r 2 2 + 8r 2 = 5676/44
r 2 2 + 8r 2 = 129 – 64
r 2 2 + 8r 2 – 65 = 0
r 2 2 + 13r 2 – 5r 2 – 65 = 0
r 2 (r 2 + 13) – 5(r 2 + 13) = 0
(r 2 – 5)(r 2 + 13) = 0
r 2 = 5, r 2 = -13
Hence, the radius of the other circular end is 5 cm.
10. If the curved surface area of a right circular cone is 10010 cm 2 and its radius is 35 cm, find the volume of the cone.
Radius of the circular base of a cone = r = 35 cm
Let h and l be the height and slant height of the right circular cone.
Also, given that the curved surface area = 10010 cm 2
πrl = 10010
(22/7) × 35 × l = 10010
l = (10010 × 7)/ (22 × 35)
As we know, l 2 = r 2 + h 2
h 2 = l 2 – r 2
= (91) 2 – (35) 2
= 8281 – 1225
Volume of the cone = (1/3) πr 2 h
= (1/3) × (22/7) × 35 × 35 × 84
Hence, the volume of the right circular cone is 107800 cm 3 .

What is Volume?
- Volume is the amount of space that is inside a 3 dimensional shape.
- Because it is an amount of space, it has to be measured in cubes.
- If the shape is measured in cm, then the volume would be measured in cubic cm or cm 3
- If the shape is measured in inches, then the volume would be measured in cubic inches or in 3
Volume of a Rectangular Prism
- The volume of a rectangular prism is the number of cubes it is made from.
- To find the number of cubes, we need to multiply the length by the width by the height.
- So Volume = length x width x height or l x w x h.
- We could also multiply the area of the base (which is the length x width) by the height.
- So Volume = l x w x h or b x h (where b is the area of the base)
In the example above, the length is 3, the width is 6 and the height is 2.
So the volume is 3 x 6 x 2 = 36cm 3 or 36 cubic cm.
This tells us that there are 36 cm cubes that make up the shape.

Find Volume and Surface Area of Rectangular Solids
A cheerleading coach is having the squad paint wooden crates with the school colors to stand on at the games. (See Figure \(\PageIndex{1}\)). The amount of paint needed to cover the outside of each box is the surface area , a square measure of the total area of all the sides. The amount of space inside the crate is the volume, a cubic measure.
Figure \(\PageIndex{1}\) - This wooden crate is in the shape of a rectangular solid.
Each crate is in the shape of a rectangular solid . Its dimensions are the length, width, and height. The rectangular solid shown in Figure \(\PageIndex{2}\) has length 4 units, width 2 units, and height 3 units. Can you tell how many cubic units there are altogether? Let’s look layer by layer.
Figure \(\PageIndex{2}\) - Breaking a rectangular solid into layers makes it easier to visualize the number of cubic units it contains. This 4 by 2 by 3 rectangular solid has 24 cubic units.
Altogether there are 24 cubic units. Notice that 24 is the length × width × height.
The volume, V, of any rectangular solid is the product of the length, width, and height.
We could also write the formula for volume of a rectangular solid in terms of the area of the base. The area of the base, B, is equal to length × width.
\[B = L \cdot W\]
We can substitute B for L • W in the volume formula to get another form of the volume formula.
\[\begin{split} V &= \textcolor{red}{L \cdot W} \cdot H \\ V &= \textcolor{red}{(L \cdot W)} \cdot H \\ V &= \textcolor{red}{B} h \end{split}\]
We now have another version of the volume formula for rectangular solids. Let’s see how this works with the 4 × 2 × 3 rectangular solid we started with. See Figure \(\PageIndex{3}\).
Figure \(\PageIndex{3}\)
To find the surface area of a rectangular solid, think about finding the area of each of its faces. How many faces does the rectangular solid above have? You can see three of them.
\[\begin{split} A_{front} &= L \times W \qquad A_{side} = L \times W \qquad A_{top} = L \times W \\ A_{front} &= 4 \cdot 3 \qquad \quad \; A_{side} = 2 \cdot 3 \qquad \quad \; A_{top} = 4 \cdot 2 \\ A_{front} &= 12 \qquad \qquad A_{side} = 6 \qquad \qquad \; \; A_{top} = 8 \end{split}\]
Notice for each of the three faces you see, there is an identical opposite face that does not show.
\[\begin{split} S &= (front + back)+(left\; side + right\; side) + (top + bottom) \\ S &= (2 \cdot front) + (2 \cdot left\; side) + (2 \cdot top) \\ S &= 2 \cdot 12 + 2 \cdot 6 + 2 \cdot 8 \\ S &= 24 + 12 + 16 \\ S &= 52\; sq.\; units \end{split}\]
The surface area S of the rectangular solid shown in Figure \(\PageIndex{3}\) is 52 square units.
In general, to find the surface area of a rectangular solid, remember that each face is a rectangle, so its area is the product of its length and its width (see Figure \(\PageIndex{4}\)). Find the area of each face that you see and then multiply each area by two to account for the face on the opposite side.
\[S = 2LH + 2LW + 2WH\]
Figure \(\PageIndex{4}\) - For each face of the rectangular solid facing you, there is another face on the opposite side. There are 6 faces in all.
Definition: Volume and Surface Area of a Rectangular Solid
For a rectangular solid with length L, width W, and height H:
Example \(\PageIndex{1}\):
For a rectangular solid with length 14 cm, height 17 cm, and width 9 cm, find the (a) volume and (b) surface area.
Step 1 is the same for both (a) and (b), so we will show it just once.
Exercise \(\PageIndex{1}\):
Find the (a) volume and (b) surface area of rectangular solid with the: length 8 feet, width 9 feet, and height 11 feet.
Exercise \(\PageIndex{2}\):
Find the (a) volume and (b) surface area of rectangular solid with the: length 15 feet, width 12 feet, and height 8 feet.
1,440 cu. ft
Example \(\PageIndex{2}\):
A rectangular crate has a length of 30 inches, width of 25 inches, and height of 20 inches. Find its (a) volume and (b) surface area.
Exercise \(\PageIndex{3}\):
A rectangular box has length 9 feet, width 4 feet, and height 6 feet. Find its (a) volume and (b) surface area.
Exercise \(\PageIndex{4}\):
A rectangular suitcase has length 22 inches, width 14 inches, and height 9 inches. Find its (a) volume and (b) surface area.
2,772 cu. in
1,264 sq. in.
Volume and Surface Area of a Cube
A cube is a rectangular solid whose length, width, and height are equal. See Volume and Surface Area of a Cube, below. Substituting, s for the length, width and height into the formulas for volume and surface area of a rectangular solid, we get:
\[\begin{split} V &= LWH \quad \; S = 2LH + 2LW + 2WH \\ V &= s \cdot s \cdot s \quad S = 2s \cdot s + 2s \cdot s + 2s \cdot s \\ V &= s^{3} \qquad \quad S = 2s^{2} + 2s^{2} + 2s^{2} \\ &\qquad \qquad \quad \; S = 6s^{2} \end{split}\]
So for a cube, the formulas for volume and surface area are V = s 3 and S = 6s 2 .
Definition: Volume and Surface Area of a Cube
For any cube with sides of length s,
Example \(\PageIndex{3}\):
A cube is 2.5 inches on each side. Find its (a) volume and (b) surface area.

SOLVING VOLUME PROBLEMS
When we solve a real-world problem involving the volume of a prism, we can choose to use either of the volume formulas we know.
Example 1 :
A terrarium is shaped like a rectangular prism. The prism is 25 inches long, 13 inches wide, and 16 inches deep. What is the volume of the terrarium ?
From the given information, we can have the following figure.
Step 2 :
In the above figure, the base is in the shape of a rectangle with length 25 inches and width 13 inches.
Therefore,
Area of the base = length x width
Area of the base = 25 x 13
Area of the base = 325 square inches.
Step 3 :
Volume of the terrarium = Volume of rectangular prism
Volume of the terrarium = Base area x Height
Volume of the terrarium = 325 x 16
Volume of the terrarium = 5200 cubic inches
Example 2 :
A rectangular swimming pool is 15 meters long, 10 1/ 2 meters wide, and 2 1/ 2 meters deep. What is its volume?
In the above figure, the base is in the shape of a rectangle with length 15 meters and width 10 1/2 meters.
Area of the base = 15 x 10 1/2
Area of the base = 15 x 10.5
Area of the base = 157.5
Area of the base = 157.5 square inches.
Volume of swimming pool = Volume of rectangular prism
Volume of the swimming pool = Base area x Height
Volume of the swimming pool = 157.5 x 2 1/2
Volume of the swimming pool = 157.5 x 2.5
Volume of the swimming pool = 393.75
Volume of the swimming pool = 393 75/100
Volume of the swimming pool = 393 3/4 cubic meters

ChatGPT’s Next Magic Trick Is Singing and Solving Math Problems With Your Phone Camera
GPT-4o responds as fast as humans.
ChatGPT 4 may still be relatively new, but OpenAI is already iterating with an upgrade that can respond as quickly as humans do in normal conversation. The company showed off GPT-4o in a live demo , showing off its ability to use your phone’s camera to solve math equations and deliver a much more conversational voice assistant experience.
While we only have the event demo to go off of, GPT-4o looks impressive. It doesn’t even have to wait for you to finish your request and can roll with interruptions mid-prompt, bringing one step closer to living out Her in real life.
Even Faster Response Times
According to OpenAI, the GPT-4o model can respond as fast as 232 milliseconds to audio inputs. More realistically, it averages around 320 milliseconds to respond, which OpenAI said is similar to how fast humans respond in conversation.
On top of the speed, GPT-4o can handle interruptions and any adjustment requests. As seen in the bedtime story demo, GPT-4o immediately stopped talking when interrupted and quickly handled requests like adding more dramatic inflections, narrating in a robot voice, and even singing the entire prompt out loud. If that demo doesn’t convince you, two GPT-4o models improvising a song together should.
GPT-4o isn’t just more responsive to voice, it can also see better. The new vision features allow it to see through your device’s camera and understand things like handwritten math equations or messages . It’s eerie how genuinely touched GPT-4o sounds when it sees and understands a message that says “I Heart ChatGPT.” Even more impressive, GPT-4o can handle coding tasks and live translations between two people. This should feel way more natural than Google Translate when you’re trying to have a conversation in a foreign country.
Available for Free
OpenAI said the text and image capabilities for GPT-4o roll out today, but the voice feature will be coming to alpha within ChatGPT Plus in the coming weeks. Once it’s fully ready, the upgraded ChatGPT model will be available to all users, subscribers or otherwise. However, if you pay $20 per month for ChatGPT Plus , you’ll get five times the message limits of GPT-4o compared to the free version.
Anytime a large language model gets such an impressive update, we have to consider the potential for misuse . Considering how smoothly the live demo for solving the equation went, it looks like an even better way to help students get out of their math homework. However, OpenAI said that GPT-4o was built with new safety systems to offer guardrails on voice outputs. We’ll have to wait and see if these guardrails are enough.

Teens come up with trigonometry proof for Pythagorean Theorem, a problem that stumped math world for centuries
By Bill Whitaker
May 5, 2024 / 7:00 PM EDT / CBS News
As the school year ends, many students will be only too happy to see math classes in their rearview mirrors. It may seem to some of us non-mathematicians that geometry and trigonometry were created by the Greeks as a form of torture, so imagine our amazement when we heard two high school seniors had proved a mathematical puzzle that was thought to be impossible for 2,000 years.
We met Calcea Johnson and Ne'Kiya Jackson at their all-girls Catholic high school in New Orleans. We expected to find two mathematical prodigies.
Instead, we found at St. Mary's Academy , all students are told their possibilities are boundless.
Come Mardi Gras season, New Orleans is alive with colorful parades, replete with floats, and beads, and high school marching bands.
In a city where uniqueness is celebrated, St. Mary's stands out – with young African American women playing trombones and tubas, twirling batons and dancing - doing it all, which defines St. Mary's, students told us.
Junior Christina Blazio says the school instills in them they have the ability to accomplish anything.
Christina Blazio: That is kinda a standard here. So we aim very high - like, our aim is excellence for all students.
The private Catholic elementary and high school sits behind the Sisters of the Holy Family Convent in New Orleans East. The academy was started by an African American nun for young Black women just after the Civil War. The church still supports the school with the help of alumni.
In December 2022, seniors Ne'Kiya Jackson and Calcea Johnson were working on a school-wide math contest that came with a cash prize.
Ne'Kiya Jackson: I was motivated because there was a monetary incentive.
Calcea Johnson: 'Cause I was like, "$500 is a lot of money. So I-- I would like to at least try."
Both were staring down the thorny bonus question.
Bill Whitaker: So tell me, what was this bonus question?
Calcea Johnson: It was to create a new proof of the Pythagorean Theorem. And it kind of gave you a few guidelines on how would you start a proof.
The seniors were familiar with the Pythagorean Theorem, a fundamental principle of geometry. You may remember it from high school: a² + b² = c². In plain English, when you know the length of two sides of a right triangle, you can figure out the length of the third.
Both had studied geometry and some trigonometry, and both told us math was not easy. What no one told them was there had been more than 300 documented proofs of the Pythagorean Theorem using algebra and geometry, but for 2,000 years a proof using trigonometry was thought to be impossible, … and that was the bonus question facing them.
Bill Whitaker: When you looked at the question did you think, "Boy, this is hard"?
Ne'Kiya Jackson: Yeah.
Bill Whitaker: What motivated you to say, "Well, I'm going to try this"?
Calcea Johnson: I think I was like, "I started something. I need to finish it."
Bill Whitaker: So you just kept on going.
Calcea Johnson: Yeah.
For two months that winter, they spent almost all their free time working on the proof.
CeCe Johnson: She was like, "Mom, this is a little bit too much."
CeCe and Cal Johnson are Calcea's parents.
CeCe Johnson: So then I started looking at what she really was doing. And it was pages and pages and pages of, like, over 20 or 30 pages for this one problem.
Cal Johnson: Yeah, the garbage can was full of papers, which she would, you know, work out the problems and-- if that didn't work she would ball it up, throw it in the trash.
Bill Whitaker: Did you look at the problem?
Neliska Jackson is Ne'Kiya's mother.
Neliska Jackson: Personally I did not. 'Cause most of the time I don't understand what she's doing (laughter).
Michelle Blouin Williams: What if we did this, what if I write this? Does this help? ax² plus ….
Their math teacher, Michelle Blouin Williams, initiated the math contest.
Bill Whitaker: And did you think anyone would solve it?
Michelle Blouin Williams: Well, I wasn't necessarily looking for a solve. So, no, I didn't—
Bill Whitaker: What were you looking for?
Michelle Blouin Williams: I was just looking for some ingenuity, you know—
Calcea and Ne'Kiya delivered on that! They tried to explain their groundbreaking work to 60 Minutes. Calcea's proof is appropriately titled the Waffle Cone.
Calcea Johnson: So to start the proof, we start with just a regular right triangle where the angle in the corner is 90°. And the two angles are alpha and beta.
Bill Whitaker: Uh-huh
Calcea Johnson: So then what we do next is we draw a second congruent, which means they're equal in size. But then we start creating similar but smaller right triangles going in a pattern like this. And then it continues for infinity. And eventually it creates this larger waffle cone shape.
Calcea Johnson: Am I going a little too—
Bill Whitaker: You've been beyond me since the beginning. (laughter)
Bill Whitaker: So how did you figure out the proof?
Ne'Kiya Jackson: Okay. So you have a right triangle, 90° angle, alpha and beta.
Bill Whitaker: Then what did you do?
Ne'Kiya Jackson: Okay, I have a right triangle inside of the circle. And I have a perpendicular bisector at OP to divide the triangle to make that small right triangle. And that's basically what I used for the proof. That's the proof.
Bill Whitaker: That's what I call amazing.
Ne'Kiya Jackson: Well, thank you.
There had been one other documented proof of the theorem using trigonometry by mathematician Jason Zimba in 2009 – one in 2,000 years. Now it seems Ne'Kiya and Calcea have joined perhaps the most exclusive club in mathematics.
Bill Whitaker: So you both independently came up with proof that only used trigonometry.
Ne'Kiya Jackson: Yes.
Bill Whitaker: So are you math geniuses?
Calcea Johnson: I think that's a stretch.
Bill Whitaker: If not genius, you're really smart at math.
Ne'Kiya Jackson: Not at all. (laugh)
To document Calcea and Ne'Kiya's work, math teachers at St. Mary's submitted their proofs to an American Mathematical Society conference in Atlanta in March 2023.
Ne'Kiya Jackson: Well, our teacher approached us and was like, "Hey, you might be able to actually present this," I was like, "Are you joking?" But she wasn't. So we went. I got up there. We presented and it went well, and it blew up.
Bill Whitaker: It blew up.
Calcea Johnson: Yeah.
Ne'Kiya Jackson: It blew up.
Bill Whitaker: Yeah. What was the blowup like?
Calcea Johnson: Insane, unexpected, crazy, honestly.
It took millenia to prove, but just a minute for word of their accomplishment to go around the world. They got a write-up in South Korea and a shout-out from former first lady Michelle Obama, a commendation from the governor and keys to the city of New Orleans.
Bill Whitaker: Why do you think so many people found what you did to be so impressive?
Ne'Kiya Jackson: Probably because we're African American, one. And we're also women. So I think-- oh, and our age. Of course our ages probably played a big part.
Bill Whitaker: So you think people were surprised that young African American women, could do such a thing?
Calcea Johnson: Yeah, definitely.
Ne'Kiya Jackson: I'd like to actually be celebrated for what it is. Like, it's a great mathematical achievement.
Achievement, that's a word you hear often around St. Mary's academy. Calcea and Ne'Kiya follow a long line of barrier-breaking graduates.
The late queen of Creole cooking, Leah Chase , was an alum. so was the first African-American female New Orleans police chief, Michelle Woodfork …
And judge for the Fifth Circuit Court of Appeals, Dana Douglas. Math teacher Michelle Blouin Williams told us Calcea and Ne'Kiya are typical St. Mary's students.
Bill Whitaker: They're not unicorns.
Michelle Blouin Williams: Oh, no no. If they are unicorns, then every single lady that has matriculated through this school is a beautiful, Black unicorn.
Pamela Rogers: You're good?
Pamela Rogers, St. Mary's president and interim principal, told us the students hear that message from the moment they walk in the door.
Pamela Rogers: We believe all students can succeed, all students can learn. It does not matter the environment that you live in.
Bill Whitaker: So when word went out that two of your students had solved this almost impossible math problem, were they universally applauded?
Pamela Rogers: In this community, they were greatly applauded. Across the country, there were many naysayers.
Bill Whitaker: What were they saying?
Pamela Rogers: They were saying, "Oh, they could not have done it. African Americans don't have the brains to do it." Of course, we sheltered our girls from that. But we absolutely did not expect it to come in the volume that it came.
Bill Whitaker: And after such a wonderful achievement.
Pamela Rogers: People-- have a vision of who can be successful. And-- to some people, it is not always an African American female. And to us, it's always an African American female.
Gloria Ladson-Billings: What we know is when teachers lay out some expectations that say, "You can do this," kids will work as hard as they can to do it.
Gloria Ladson-Billings, professor emeritus at the University of Wisconsin, has studied how best to teach African American students. She told us an encouraging teacher can change a life.
Bill Whitaker: And what's the difference, say, between having a teacher like that and a whole school dedicated to the excellence of these students?
Gloria Ladson-Billings: So a whole school is almost like being in Heaven.
Bill Whitaker: What do you mean by that?
Gloria Ladson-Billings: Many of our young people have their ceilings lowered, that somewhere around fourth or fifth grade, their thoughts are, "I'm not going to be anything special." What I think is probably happening at St. Mary's is young women come in as, perhaps, ninth graders and are told, "Here's what we expect to happen. And here's how we're going to help you get there."
At St. Mary's, half the students get scholarships, subsidized by fundraising to defray the $8,000 a year tuition. Here, there's no test to get in, but expectations are high and rules are strict: no cellphones, modest skirts, hair must be its natural color.
Students Rayah Siddiq, Summer Forde, Carissa Washington, Tatum Williams and Christina Blazio told us they appreciate the rules and rigor.
Rayah Siddiq: Especially the standards that they set for us. They're very high. And I don't think that's ever going to change.
Bill Whitaker: So is there a heart, a philosophy, an essence to St. Mary's?
Summer Forde: The sisterhood—
Carissa Washington: Sisterhood.
Tatum Williams: Sisterhood.
Bill Whitaker: The sisterhood?
Voices: Yes.
Bill Whitaker: And you don't mean the nuns. You mean-- (laughter)
Christina Blazio: I mean, yeah. The community—
Bill Whitaker: So when you're here, there's just no question that you're going to go on to college.
Rayah Siddiq: College is all they talk about. (laughter)
Pamela Rogers: … and Arizona State University (Cheering)
Principal Rogers announces to her 615 students the colleges where every senior has been accepted.
Bill Whitaker: So for 17 years, you've had a 100% graduation rate—
Pamela Rogers: Yes.
Bill Whitaker: --and a 100% college acceptance rate?
Pamela Rogers: That's correct.
Last year when Ne'Kiya and Calcea graduated, all their classmates went to college and got scholarships. Ne'Kiya got a full ride to the pharmacy school at Xavier University in New Orleans. Calcea, the class valedictorian, is studying environmental engineering at Louisiana State University.
Bill Whitaker: So wait a minute. Neither one of you is going to pursue a career in math?
Both: No. (laugh)
Calcea Johnson: I may take up a minor in math. But I don't want that to be my job job.
Ne'Kiya Jackson: Yeah. People might expect too much out of me if (laugh) I become a mathematician. (laugh)
But math is not completely in their rear-view mirrors. This spring they submitted their high school proofs for final peer review and publication … and are still working on further proofs of the Pythagorean Theorem. Since their first two …
Calcea Johnson: We found five. And then we found a general format that could potentially produce at least five additional proofs.
Bill Whitaker: And you're not math geniuses?
Bill Whitaker: I'm not buying it. (laughs)

This paper presents and examines a newly improved linear technique for solving the equilibrium problem of a pseudomonotone operator and the fixed point problem of a nonexpansive mapping within a real Hilbert space framework. The technique relies two modified mildly inertial methods and the subgradient extragradient approach. In addition, it can be viewed as an advancement over the previously known inertial subgradient extragradient approach. Based on common assumptions, the algorithm's weak convergence has been established. Finally, in order to confirm the efficiency and benefit of the proposed algorithm, we present a few numerical experiments.

What Is Tucker Carlson Even Doing?
His post–fox news years did not look promising. they’ve been bleak beyond imagination..
This is part of Sly as Fox , a short series about the perils of underestimating Fox News in 2024.
It is always sort of heartwarming when a person fulfills their peak potential. Many of us never do so, after all, and instead spend our lives caught in the frustrating gap between ability and opportunity. When someone is able to bridge that gap and become their optimal self, it should count as cause for celebration. And so I am genuinely glad to see that former Fox News host Tucker Carlson is now doing the work that he was always meant to do: posting crackpot videos to the internet for an audience of angry loons.
It presumably came as the shock of Carlson’s life when, in April 2023, he was abruptly ousted from Fox News upon the sudden cancellation of his prime-time program there, Tucker Carlson Tonight . After all, Carlson was the unquestioned alpha of Fox’s talent roster, and his show often rated as the most popular prime-time show in all of cable television. He used his platform for many interesting purposes: to applaud political strongmen, to whitewash the events of Jan. 6, and to propagate a series of dark ethnonationalist theories that echoed themes long sounded in the least reputable corners of the internet. His formula was “Trumpism without Trump,” as the New York Times put it in a long 2022 profile, and it worked very well—right up until the day when his bosses, for whatever reason, decided that they had had enough.
While the justifications for his departure remain murky, the ramifications were as clear as day. Carlson was off the air, and because he was still under contract to Fox News—the contract reportedly runs through 2024 —he could not seek employment at another media outlet. Sidelined on the brink of a general-election campaign, facing sudden irrelevance upon the loss of his prominent platform, Carlson decided to follow in the footsteps of many deposed mainstream-media icons before him: He took his talents online.
Within weeks of leaving Fox News, Carlson announced that he would independently produce a version of his show for broadcast on Twitter, now “X,” a website that is not known for having shows. In the first episode , he pretty much picked up where he had left off on cable: carrying water for Vladimir Putin, sneering at mainstream-media groupthink, and calling Ukrainian president Volodymyr Zelensky, who is Jewish, “sweaty and rat-like, a comedian turned oligarch, a persecutor of Christians, a friend of BlackRock.” There’s, uh, a lot to parse there.
According to Twitter, Carlson’s debut logged 114 million views within a week of its release—a number that seems much less impressive when you realize that a “view” only means that a logged-in user watched at least 2 seconds of a video with at least half of the video player visible on the user’s screen. This inaugural episode was met with a cease-and-desist letter from Fox News, and while Carlson neither ceased nor desisted, it ultimately didn’t matter, because “Tucker on Twitter” did not sustain its initial momentum.
Carlson seemed to be learning the same hard lesson that many other would-be multiplatform demagogues have learned: The internet is already oversaturated with perfervid dog-whistling about shadowy globalist cabals. Carlson’s VDARE-lite punditry was a novelty on mainstream cable television. On Twitter, though, he was just another wingnut with a webcam. But rather than reading the room and deciding to sit back and count his money while waiting for his Fox contract to expire, Carlson instead chose to double down on his online ventures.
In December 2023, with seed capital from an “anti-woke” venture capital firm and in collaboration with his college roommate and co-founder of the Daily Caller, Neil Patel, and the former executive producer of his Fox News show, Justin Wells, Carlson launched a website called the “Tucker Carlson Network,” or TCN—not to be confused with the cable network TC M , which also likes to present things in black and white. (On Wednesday, Semafor reported that Wells is leaving TCN.)
I spent much of this past week poking around on TCN, which is perhaps best understood as a streaming service meant for the sorts of people who thought Heather Heyer had it coming. While I do not fully understand how this venture is allowable under the terms of Carlson’s Fox News contract, I suppose it’s possible that Fox took a look at TCN’s output and decided that there are some eyeballs that just aren’t worth competing for.
The website features various Tucker-centric programs covering various Tucker-approved topics, such as systemic racism against white Americans , the Biden administration’s alleged war on Christianity , and the many ways in which the QAnon Shaman got jobbed by the feds. Some TCN content is paywalled, and to access it you have to subscribe , for either $9 per month or $72 per year. Your subscription also buys you other perks, such as the opportunity to ask the host questions that he might subsequently choose to answer on camera, in an advice segment called Ask Tucker . (“I want to discipline my kids but I’m worried about turning into Tony Fauci . What do I do?”) The network’s logo resembles a “red pill,” as in the metaphorical medicine that alt-right podcasters urge their listeners to swallow so that they might stop feeling bad about being bigoted incels.
TCN’s shows are all pretty similar. Carlson opines on current events and conducts interviews with an ideologically predictable roster of guests, such as mixed martial artist and alleged cultural cancelee Gina Carano ; former Times reporter turned vaccine skeptic Alex Berenson ; Joe Biden sexual-assault accuser Tara Reade ; and Twitter user Catturd . He also interviewed the notorious mid-2000s internet jackass Tucker Max , whom Carlson inaccurately described as being a “beautiful prose stylist.” (I suppose I should not be surprised that America’s two most irritating Tuckers know each other.) Carlson also interviews heavier hitters, such as Andrew and Tristan Tate , the sibling social-media influencers who are each currently facing rape and human trafficking charges in Romania; Jeffrey Epstein’s brother Mark , who refused to appear on camera; and Vladimir Putin, whom Carlson traveled to Russia to meet earlier this year, and who subsequently disparaged the host for conducting a softball interview.
Putin was a big “get” for Carlson, no doubt about it, even if the interview made the host look more like a credulous tourist than a serious journalist. And yet most of Carlson’s guests on TCN are neither as prominent nor as important as Putin. The host isn’t sitting down with world leaders every week; he’s sitting down with the sorts of guests whom you can also find on plenty of other alt-right online shows and podcasts. After poking around the Tucker Carlson Network for the better part of a week, I couldn’t help but wonder: Who, exactly, is the website for?
Earlier in this column I speculated that Carlson’s audience was made up of angry loons—but as I already mentioned, there’s already a lot of competition online for these people’s attention, and many of these outlets do not require said loons to spend $9 per month to get their cortisol fix. “The whole vision is to create the next media company that is purpose-built for the 2020s and 2030s,” one of Carlson’s financiers told the Wall Street Journal . The pitch seemed somehow both ominous and empty, much like many of Carlson’s monologues. I might not be an anti-woke VC, but I do know enough about media to say that actual next-generation media companies generally aren’t built around middle-aged race-baiters interviewing cranks and weirdos from their paneled living room. That’s a podcast, not a viable startup.
Podcasts and online shows can be lucrative, that’s for sure, and perhaps Carlson’s intention is simply to bigfoot some of the other alt-right commentators who have staked their claims in that space. But to play in the same sandbox as people such as Joe Rogan and Alex Jones—in a recent appearance on Rogan’s show, Carlson implied that Jones may be some sort of prophet—Carlson’s going to have to keep matching or exceeding them thematically. The farther he goes over into true wingnut territory, the harder it becomes to build an actual media company around him.
What’s Carlson’s endgame here? A March interview that Carlson conducted with ex-CNN guy and current NewsNation host Chris Cuomo perhaps offers a clue. It ran for almost two hours, and while I confess to only skipping around in it instead of watching the whole thing, the unmistakable impression I got from the conversation is that these are two guys who really miss their old platforms. Seen in that context, you begin to understand that the Tucker Carlson Network is primarily meant for Tucker Carlson himself. It’s a vanity project designed to keep the host busy as he counts down the days to when he can return to cable once again.
For now, though, he’s working hard to remake his cable persona for the needs and desires of the alt-right internet. Although a new program called The Tucker Carlson Show just launched this week—Carlson’s first two guests were podcaster Dave Smith and ayahuasca enthusiast Aaron Rodgers , who announced , inaccurately, that Carlson’s interview with Putin had been “awesome”—TCN’s flagship show up to now has been Tucker Carlson Uncensored , in which the host monologues a bit and then generally chats with a guest. While the show’s title implies that the host was in fact censored in his previous job, the Tucker Carlson Uncensored episodes I watched were all thematically similar to his Fox News output.
If there is a discernable difference between this new, free-to-speak-his-mind version of Carlson and his ostensibly muzzled predecessor, I suppose it is that Uncensored Tucker hardly even bothers to camouflage his true opinions and intentions. The Ukraine skepticism and careful Putin apologism that pervaded the last year or so of his Fox show has become a full-fledged effort to portray Ukraine as the real enemy . And while Carlson spent countless hours on Fox News fanning the flames of xenophobic nativism, on Uncensored he’s doing stuff like interviewing white nationalist Lydia Brimelow. You get the picture. Carlson is no longer wasting any time trying to hide the ball, which I suppose is why I’m happy for him. In becoming an internet video guy, Carlson has emerged fully from the shadows and stepped fully into the unflattering light of his own biases. There is something to be said for self-actualization—if only so that the rest of us can see who someone’s true self was all along.
