Here's what I came up with. 35ft X 50ft = 1750 sq ft and1750 cubit feet. 3 inches is 1/4 of a cubic foot so divide 1750 by 4. This gives you 437.5 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 437.5 by 27. This give you 16.2 cubic yards.
Hope this helps.
You would need 31.88 cubic yards of topsoil to cover 855 sq feet at 6 inches deep.
To determine the amount of topsoil needed for one acre at a depth of 4 inches, first convert the depth from inches to feet: 4 inches is 1/3 of a foot. There are 43,560 square feet in an acre, so the volume in cubic feet is 43,560 sq ft * (1/3 ft) = 14,520 cubic feet. Since there are 27 cubic feet in a cubic yard, divide by 27 to find the volume in cubic yards: 14,520 / 27 ≈ 538.89 cubic yards. Therefore, you will need approximately 539 cubic yards of topsoil.
For 2 feet deep, you need 230 cu. yds (3100 x 2) / (27) For 2 inches deep, you need 19 cu yds
It takes 5.0926 cubic yards or 137.5 cubic feet.
1 cubic yard = 27 cubic feet6 inches = 1/2 footVolume = (45-ft x 30-ft x 1/2-ft) = 675 cubic feet = 25 cubic yards.

3100 x 5/12 = 1292 cubic feet Since one yard = 27 cu ft, you need about 1292/27 = 48 yards
