You also need to specify the average depth.
(And by "yards" we assume you mean cubic yards).
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.
how much sand and other humous is in the dirt ??
1 square yard = 9 square feet so 195 sq feet = 195/9 sq yards = 21.66... sq yards.
133.33 cubic yards, that's 400 feet
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.
259.2593 sq. yards.
Sorry the first answer was in square yds. Cubic yards would be 0.308639
None because it's a hole but 6 cubic yards of dirt will fill it up.
18 cubic feet
It depends on whether the dimensions given are in feet or yards or metres or some other unit.
About 3 yards with a little left over. 2.78 yards.
This is a nonsense question. Tons of dirt can be converted to cubic feet, depending on moisture and dirt type, but not to sf or square feet.
