a gallon of paint can cover about 350 square feet of wall space. You have measured a wall to be 210 inches by 120 inches. Will one gallon of paint be enough to cover the wall?

1 foot = 12 inches.

210/12 = 17.5 feet

120/12 = 10 feet

17.5 x 10 = 175 square feet

175 is less than 350 so yes one gallon will be enough.
