Each gallon of paint covers 200 square feet. I have to paint one side of a wall that is 12 meters tall and 80 meters long. If a foot is approximately 0.3048 meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?
Thx
The wall is 12*80 = 960 m^2. This converts to 960/0.3048 = 3150 square feet, so the number of gallons needed is 3150/200 = 15.74, which rounds up to 16.
+9479 The total surface area to paint = 12 m * 80 m = 960 square meters
1 ft ≈ 0.3048 m
1 ft2 ≈ 0.09290304 m2
200 ft2 ≈ 18.580608 m2
And so one gallon of paint covers about 18.581 square meters.
960 m2 / ( 18.581 m2 per gallon) ≈ 51.67 gallons
So 51 gallons would not be enough... it would take 52 gallons of paint to cover the wall.
(Note to previous answerer: 960 m2 ≈ 10333.354 ft2 ≉ 3150 ft2)
