How Do You Find the Volume of a Cube?

The conventional method for finding the volume of a cube involves taking the length of one side and cubing it. “V = s^3” (Volume equals one side to the third power) is the algebraic expression for finding the volume of a cube. As an example, if you have a cube with a height of 10 inches, you must first find the area of the base (10 x 10, or 100 square inches). Once you have the area of the base, simply multiply it by the length of the side once more (100 x 10, or 1,000 cubed inches).

Instructions

1. Find the length of one of the sides of the cube. The sides of a cube are identical in length, so it doesn’t matter which side you use.

2. Multiply the side’s length by itself. For example, if one side is 5 inches long, you'd multiply 5 x 5. The area of the base of the cube is 25 square inches.

3. Multiply the number you got in step two by the original number (5 for this example--V = 25 x 5). The volume of a 5 x 5 cube is 125 cubed inches.
