### Example Question #981 : Intermediate Geometry

A cubic swimming pool has edge lengths of . In meters, how deep will the pool be if  of water is added to the pool?

Explanation:

We have the length, the width, and the volume for this cube. We just need to figure out the height.

Recall how to find the volume of a cube:

Normally, these three values would be the same. However, in this case, since the pool is not being filled up the entire way, the height of the cube will be different from its length and width.

The pool will be  meters deep.

### Example Question #982 : Intermediate Geometry

If a cube has a volume of , what would be the length of the sides of the cube?
