    Answer: 31.5 rolls

    Step-by-step explanation:

    A room is to be wallpapered including the ceiling and floor and the room is 18 feet long by 10 feet wide by 7 feet high. The total area covered by the room will be: length * width * height

    = 18 * 10 * 7

    = 1260 feet

    A roll of wallpaper covers 40 ft. The number of rolls to buy will be:

    = 1260 : 40

    = 31.5 rolls
