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.

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

15• 144= 2160 sq inches

2160/180= 12 hours

To find the number of hours it will take you to paint the wall, we need to convert the area of the wall from square feet to square inches.

First, we convert 15 square feet to square inches:
1 square foot = 12*12 = 144 square inches
So, 15 square feet = 15 * 144 = 2160 square inches.

Next, we divide the total area of the wall by the painting rate of 180 square inches per hour to determine the number of hours needed:
2160 square inches ÷ 180 square inches per hour = 12 hours.

Therefore, it will take you approximately 12 hours to paint the wall.
