Answer 2

First: Please note that volume here is measured in cubic feet: 72 cubic feet, not 72 feet.
Second: Note that you have two different problems here, and need to separate them accordingly.
Third: Drawing a picture in each case would likely help you greatly in visualizing what needs to be done.
