+27 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?
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.
+37153 12 x 80 = 960 m2
960 m2 / [( .3048 m/ft)(.3048 m/ft)] = 10333.35 ft2
10333.354 ft2 / 200ft2/gal = 51.667 gal =~~52 gallons
