You can't fill a space with yards, only with cubic yards (27 cu.ft.).
28 x 12 x 1/3 = 112 cubic feet / 27 cubic feet = 4.148148...cubic yards will be required.
1.851852 cubic yards
if that is 3 ft deep it would require 96 yards... IF it is 3 inches deep it would require 24 cubic yards

Deep space
No, not even close. Deep space would be well outside the solar system.
You would need 31.88 cubic yards of topsoil to cover 855 sq feet at 6 inches deep.
There are two end zones are on a football field.
62/3 cubic yards for every 1-foot deep. 5 cubic yards for every 9-inches deep. 31/3 cubic yards for every 6-inches deep. 5/9 cubic yard for every 1-inch deep.

That depends entirely on what kind of sand how deep you spread it. As an approximation, you could assume a bulk density for dry sand of about 110 lb/ft3. One ton (2000 lb) of sand would thus be about 18.18 ft3 or 0.673 yd3. If you spread it 6 inches deep you could cover about 4 square yards. At a foot deep, you would cover 2 square yards. At 3 inches deep you would cover 8 square yards. At 1 inch deep you would cover 24 square yards Reported bulk densities for sand range from 78 lb/ft3 for molding sand to 130 lb/ft3 for moist sand.
