There are (exactly) 3 feet per yard; therefore, the dimension of the room are 8 yd X 6 yd X 3 yd. Wall paper is not customarily used on the ceiling or floor of a room. Therefore, assuming that 3 yd is the height, the area to be covered by wallpaper is
2(6 X 3) + 2(8 X 3) = 84 square yards. The ceiling or floor would take an additional 6 X 8 = 48 square yards each if they are also to be covered.
13.333 square yards.
At least 31.77 square yards are needed.
348 square feet are 38.666667 square yards.
170/9 = 18.9 square yards
84 square yards
9 yards x 27 yards = 243 square yards.
191.54 square yards.
you will need 84 sq. yards of wallpaper
14 square yards (assuming you are purchasing whole square yards)
15 x 10 = 150 square yards
To calculate the total square yards of wallpaper needed to cover the four walls, first find the total surface area of the walls. The walls will have a total area of (2(24 \times 9) + 2(18 \times 9) = 648) square feet. Since 1 square yard is equivalent to 9 square feet, divide 648 square feet by 9 to get 72 square yards of wallpaper needed.
400 square yards. This is because there are 9 square feet in a square yard, and there are 3600 square feet of carpet needed to cover the 60' x 60' floor.
