You paint four walls. Each wall is a rectangle with a length of 24 feet and a height of 12 feet. One gallon of paint covers about 360 square feet. How many gallons of paint do you need in order to cover the walls?

Answer:

3.2 Gallons

Step-by-step explanation:

First you figure out the area of each rectangle:

24 x 12= 288 squared feet

Then multiply 288 by four (because there are four walls):

288 x 4= 1,152

Finally you divide 1,152 by 360:

1,152 ÷ 360 = 3.2

15 gallons

369 divided by 24
