+479 I have to paint one side of a wall. The wall is 12 meters tall and 120 meters long. Each gallon of paint covers 150 square feet. 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?
+57 a square foot is 0.3048 x 0.3048 = 0.09290304 square meters. The wall is 1440 square meters. A gallon covers 0.09290304 x 150 = 13.935456 square meters. So just divide 1440 by 13.935456, which is between 103 and 104(around 103 1/3), so the answer is 104
