Leon wants to paint the four walls in his dining room. Each wall is 8 feet high by 30 feet wide. A quart of paint covers 40 ft². How many gallons of paint must he purchase?

A. 6

B. 8

C. 12

D. 15

Solution

A. Leon has four walls that are 8 ft by 30 ft. That’s an area of 240 ft² for each of four walls. For all four walls, multiply 240 by 4, giving a total square footage of 960 ft². If a quart of paint covers 40 ft², then you need to divide 960 by 40, which results in 24 quarts of paint. The question asks for the number of gallons. Since there are 4 quarts in a gallon, divide 24 by 4 to get 6 gallons.
