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.

12 x 80 = 960 m^{2}

960 m^{2 }/ [( .3048 m/ft)(.3048 m/ft)] = 10333.35 ft^{2}

10333.354 ft^{2} / 200ft^{2}/gal = 51.667 gal =~~52 gallons
