The walls of a square room need painting each of four walls is 12ft wide bu 8.5 feet tall one gallon of paint covres 75ft how many gallons will you need

5.44 gallons are needed to cover 408 square feet.

Step-by-step explanation:

The walls of a room need painting. Each of the four walls is 12 ft wide by 8.5 feet tall.

We know that, Area = length  width.

So, the area of one wall = 8.5 ft  12 ft = 102 square feet

Thus, the area of 4 walls = 4  102 = 408 square feet

One gallon of paint covers 75 square feet. We need to find how many gallons of paint will cover 408 square feet.

So, the amount of gallons of paint needed = 40875

= 5.44 gallons

So, 5.44 gallons are needed to cover 408 square feet.

5.44 gallons
