Question

You paint four walls. Each wall is a rectangle with a length of 20 feet and a height of 12 feet. One gallon of paint covers about 320 square feet. How many gallons of paint do you need in order to cover the walls?

4 walls = 4 x 240 = 960 squared feet

960 divided into 320 = 3

1 gallon --------320

1 gallon------------320
