Question

a wall is 8 feet tall and 36 feet wide. tom wants to cover it with white paint that costs 2 dollars per ounce. if each ounce of paint can cover approximately 72 square inches of area, how much would it cost to buy enough paint to cover the entire wall

Answer 1

1152

Explanation:

First we need to find the area of the wall in square inches

8 ft = 8*12 = 96 inch tall

36 ft = 36 * 12 = 432 inches wide

The area = 96 * 432 =41472 in^2

Each ounce of paint cover 72 in^2 so divide by 72

41472/72 =576

We need 576 ounces to cover the wall

At 2 dollars per ounces

576*2 =1152 dollars to paint the wall
