Question

Henry is painting a room with four walls that 12 feet by 14 feet. A gallon of paint cost $18 and covers 350 square feet. If he uses two coats of paint, how much will it cost him to paint the room.

Answer 1

What is the total area he needs to paint?
If the room is 12 ft by 14 ft, and that means the width and length, we can't figure it out because we don't have the height of the walls.
