Question

Obaid wants to paint the ceiling of his restaurant. The ceiling is in the shape of a square. Its side lengths are 15 meters. Suppose each can of paint will cover 25 square meters. How many cans will he need to paint the ceiling?

Answer 1

Answer:

9 cans

Step-by-step explanation

Side length of the squared ceiling = 15m

Area of a square = side x side = 15 x 15 = $225m^{2}$

Area of paint each can covers = 25m

∴Number of paint cans needed to paint the entire ceiling = $\frac{225}{25}$ = 9 cans
