Question

the area of a wall is 15 square feet. if i can paint 180 sq inches per hour how many hour will it take me to paint the wall.

Answer 1

1 ft = 12 in

1 ft ^ 2 = ( 12 ^ 2 ) in ^ 2

1 ft ^ 2 = 144 in ^ 2



15 * 144 = 2160



15 ft ^ 2 = 2160 in ^ 2



2160 / 180 = 12



12 hours

Answer 2

15• 144= 2160 sq inches
2160/180= 12 hours
