You are mixing volume (square yard) and area (length x width). How deep do you want the dirt? One foot deep you need about 80 square yards of dirt.
You can measure the surface of the dirt in square yards. That would be nine square feet.However the volume or amount of dirt cannot be measured in square yards or square feet. The amount of dirt in a volume of one cubic yard would be 27 cubic feet. ( 3x3x3=27 )The amount of dirt in a square yard to a depth of 0.5 feet would be 4.5 cubic feet. (3x3x0.5=4.5)
Roughly 12 square yards.
Sorry the first answer was in square yds. Cubic yards would be 0.308639
When you buy yards of dirt you are really buying cubic yards. So change your dimensions to yards and multiply together; 10 x 10 x 1.33 = 133 cubic yards. So you would buy 133 yards of dirt.
It will take 800 cubic yards 1/3 compaction.
Whereas a yard is a unit of length, a square yard is a unit of area. Therefore, one cannot ask how many yards are in a square yard because the units are incompatible. Perhaps you meant to ask How many square feet are in eight square yards. Since there are nine square feet in a square yard, eight square yards equals 72 square feet. There is another unit for measuring a volume of topsoil, stone, or cement. It, too, is called a yard but is really a cubic yard. It is an amount of material that will fill a 3' x 3' x 3' space. It is equivalent to 27 cubic feet. You can see how this could lead to confusion. Perhaps you wish to cover an area of eight square yards of ground with topsoil or mulch or stone -- whatever. The material is sold by the yard, but that yard (a unit of volume) is not the same as the square yard you used to measure the area of the ground. The question would then become How many yards of dirt do you need to cover an area of eight square yards? Which prompts the question How deep do you want it?
Well, you would take the 7000 square feet of dirt and multiply it by the four inches of stone to get the 28000 cubic yards of stone. (28000 yds³)
About 3 yards with a little left over. 2.78 yards.
How many pounds are in 10 yards of dirt
Converting square yards to cubic yards is like converting apples to oranges or like converting miles per hour to kilograms. The square yard is a unit of area, whereas the cubic yard is a unit of volume. The yard: a unit of distance. The square yard: a unit of area. The cubic yard: a unit of volume. Let's think of some uses for each of those. The first one's easy. If you want to know how far it is from one goal post on a football field to the other goal post, you would use yards. If you want to know how much turf you will need to cover the field, you use square yards. If you want to know how much dirt (or gravel or Jell-O) you would need to cover the whole field to a depth of four inches, you would use cubic yards.
22.2222 cubic yards (the 2s keep on going).
You also need to specify the average depth.(And by "yards" we assume you mean cubic yards).
