Each gallon of paint covers 400 square feet. I have to paint one side of a wall that is 8 meters tall and 40 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?
8 x 40 = 320 m^2 =
320 m^2 / (.3048 m/f )^2 = 3444.45 ft^2
3444.45 ft^2 / 400 ft^2/gal = 8.61 gal =~ 9 gallons of paint required
