I need to buy 0.75 gallons of paint 2 coats on the wall.
We are given the area of wall, which is 150 square feet. So, if I need to put double or two coats on the wall, the area of wall to be considered will be : 150 × 2
Area of wall to be considered = 300 square feet
As per the information on paint -
400 square feet is covered by amount of paint = 1 gallon
300 square feet will be covered by amount of paint = (1 ÷ 400) × 300
Amount of paint = 300 ÷ 400
Amount of paint = 0.75 gallons
Therefore, I need to buy 0.75 gallons of paint 2 coats on the wall.
