A room is 13 ft. It needs to be painted. The ceiling is 8 ft above the floor. there are two windows int he room, each one is 3 ft by 4 ft. The door is 2.5 ft by 6.5 ft. What is the area of the wall and ceiling? 1 gallon of paint covers 64.37sq ft. How many gallons are needed to paint the room? At $23.48 a gallon, what is the cost to paint the room?

You only provide one linear floor and ceiling dimension, 13 ft. Unless the room is square, you need to know two: length and width.
Why do you say "wall" and not "walls" ?
