I really need help with a problem. I'm NOT asking for the answer, just some help on how to solve it.
***Pedro has a rectangular kiddie pool with a side length of 5 ft, width of 3 ft, and height of 1 1/2 ft. If the pool is only filled 1/3 full with water, how much water is in Pedro's pool?*** I really don't know how to solve this problem. Please help?
