Example Question #1 : 3 Dimensional Geometry
Figure not drawn to scale.
What is the volume of the cylinder above?
52.36 in3
48.79 in3
66.13 in3
56.55 in3
94.25 in3
56.55 in3
In order to find the volume of a cylinder, you find the area of the circular top and multiply it by the height.
The volume of the cylinder is 56.55 in3
Example Question #1 : Volume
Figure not drawn to scale
If the volume of the cone above is 47.12 ft3, what is the radius of the base?
5 ft
2 ft
3 ft
4 ft
3.5ft
3 ft
Because we have been given the volume of the cone and have been asked to find the radius of the base of the cone, we must work backwards using the volume formula.
The radius of the base of the cone is 3 ft.
Example Question #1 : Volume

What is the volume of the above image?
64 yd3
42 yd2
42 yd3
32 yd3
84 yd2
42 yd3
You can find the volume of a box by following the equation below:
The surface area of the box is 42 yd3 (remember that volume measurements are cubic units NOT square units)
Example Question #1 : Volume
A regular tetrahedron is composed of four equilateral triangles. The formula for the volume of a regular tetrahedron is:
, where represents the length of the side.
Plugging in our values we get:
Example Question #2 : Volume
Find the volume of a tetrahedron with an edge of .
Write the formula for the volume of a tetrahedron.
Substitute in the length of the edge provided in the problem.
Rationalize the denominator.
Example Question #1 : How To Find The Volume Of A Tetrahedron
Find the volume of a tetrahedron with an edge of .
Write the formula for the volume of a tetrahedron.
Substitute in the length of the edge provided in the problem:
Cancel out the in the denominator with one in the numerator:
A square root is being raised to the power of two in the numerator; these two operations cancel each other out. After canceling those operations, reduce the remaining fraction to arrive at the correct answer:

Write the formula for finding the volume of a tetrahedron.
Substitute in the edge length provided in the problem.
Cancel out the in the denominator with part of the in the numerator:
Expand, rationalize the denominator, and reduce to arrive at the correct answer:
Example Question #3 : How To Find The Volume Of A Tetrahedron
Find the volume of a tetrahedron with an edge of .
Write the formula the volume of a tetrahedron.
Substitute the edge length provided in the equation into the formula.
Cancel out the denominator with part of the numerator and solve the remaining part of the numerator to arrive at the correct answer.
Example Question #4 : How To Find The Volume Of A Tetrahedron
Find the volume of a tetrahedron with an edge of .
Write the formula the volume of a tetrahedron and substitute in the provided edge length.
Rationalize the denominator to arrive at the correct answer.
Example Question #5 : How To Find The Volume Of A Tetrahedron
Find the volume of the regular tetrahedron with side length .
