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.
84 square yards
348 square feet are 38.666667 square yards.
170/9 = 18.9 square yards
To calculate linear yards for wallpaper, first measure the height and width of each wall you plan to cover. Multiply the height by the width to find the total square footage for each wall, then sum the areas of all walls. Since wallpaper is usually sold in rolls measured in square feet, convert the total square footage to linear yards by dividing the total square footage by 9 (since one linear yard equals 3 feet). Finally, consider the pattern repeat and any waste to determine the total amount of wallpaper needed.
you will need 84 sq. yards of wallpaper
9 yards x 27 yards = 243 square yards.
191.54 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.
14 square yards (assuming you are purchasing whole square yards)
15 x 10 = 150 square yards
