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

0.3048^2 =0.09290304 m^2 per ft^2

960 / 0.09290304 =10,333 ft^2 - Area of wall to be painted.

10,333 / 200 =51.665 =~52 gallons to paint the entire wall.
