Minnie is painting her walkin
closet. Each gallon of paint
covers 275 square feet. The
closet is in the shape of a right
rectangular prism. The floor is 9 feet wide
and 7 feet long. The ceiling is 8 feet high. How
many gallons of paint should Minnie buy to cover the four
walls and the ceiling with two coats of paint?
