Question

tony wants to paint the ceiling of his restaurant. the ceiling is in the shape of a square. its side lengths are 48 feet. suppose each can of paint will cover 192 square feet. how many cans will he need to paint the ceiling?

Explanation:

Step1: Calculate ceiling area

The area of a square is $A = s^2$, where $s = 48$ feet. So $A=48\times48 = 2304$ square - feet.

Step2: Calculate number of cans

Divide the total area by the area covered by one can. Let $n$ be the number of cans. Then $n=\frac{2304}{192}=12$.

Answer:

12
