If a room is 10 feet long and 9 feet wide how much wallpaper would you need for floor?

Convert all measurements to yards by dividing by 3 (3 feet per yard). Now, there are four walls, 2 walls are 8 yards long by 3 yards high and 2 walls are 6 yards by 3 yards. So the equasion will be (2 * 8 * 3)+(2 * 6 * 3)= 84. 84 yards minimum is required to wallpaper the room. If this is not just a math question and you're really papering the room, don't forget to obtain 5-10% extra wallpaper because you're going to lose some due to mistakes and waste.
