Question

The volume of a cube is 8000 cubic feet, what is the area of one of its faces?

Answer 1

Since a cube is l x w x h, find the length of one side first:

∛8,000 = 20

The length of one side is 20 feet. This can represented as "s".

To find the area of one of the faces, use s²:

20²   or   20 x 20 = 400

The area of one face is 400 ft²!
