The problem:

The volume of a rectangular box is 192 centimeters. What is the height of the box if the area of the base is 48 square centimeters.

How do I solve this? Am I supposed to turn the square centimeters into cubic CMs? If so, how? (I know to find the volume of a rectangle to go V=lw) Am I even on the right track?

Basically I have no idea what in the world I'm doing. :D
