GIVING 25 POINTS SO HURRY.

A roll of wallpaper covers 70 square feet. Suppose a rectangular room measures 10 feet long by 12 feet wide by 8 feet high and has two windows and two doors. How many whole rolls of wallpaper are needed to wallpaper the room? Subtract 15 feet for each window and door.

First, we need to find the area of wall we need to cover. The room is 10 by 12 by 8 feet. I'm assuming that we only need to wallpaper the ceiling and side walls. It would be weird to wallpaper the floor when there is carpet/tiling.

Ceiling area: $10 \times 12 = 120$

Wall area: $2(12 \times 8)+2(10 \times 8)=352$

Total area: $120+352=472$

Now, we subtract 15 feet for each window and door. There are two windows and two doors.

$472-4(15)=412$

412 square feet of wall needs to be wallpapered. Dividing this by 70 (the square footage covered by one roll) gives something a little less than 6.

6 full rolls of wallpaper will be needed to fully wallpaper the room.
