I have to paint one side of a wall.  The wall is $15$ meters tall and $60$ meters long.  Each gallon of paint covers $400$ 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?

15 / .3048  *  60 / .3048 ≈  9688   sq ft

 

Ceiling [  9688 /  400 ] =   25 gallons
