Question

Question 15

Salma wants to paint the ceiling of her restaurant. The ceiling is in the shape of a square. Its side lengths are 44feet. Suppose each can of paint will cover 242 square feet. How many cans will she need to paint the ceiling?

Answer 1

The first thing we need to do is determine the square footage, or area, of the ceiling. Since it is a square with side length of 44 ft., we simply multiply side times side to find the area of the ceiling. 44 x 44 = 1936 sq. ft.

Now we need to divide the area of the ceiling by the number of square feet each can of paint will cover. So 1936 ÷ 242 = 8. This divides evenly, so we will need exactly 8 cans of paint to cover the ceiling. ** Note: If I was doing this paint job, I would have a 9th can on hand, just to cover for spillage, touch-up spots, etc. (-: But sticking with just the technical, mathematical side of things, 8 cans should do it!
