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 m * 60 m       *    1 ft /.3048 m   *  1 ft / .3048 m  )  /  ( 400 ft^2 / gal ) = 24.22 gal    ~~   25 gallons required
