A yard of dirt is 3ft x 3ft x 3ft, or 27 cubic ft. The hole you need to fill is 8ft x 4ft x 1ft, or 32 cubic ft. You'll need 32/27th yards of dirt, or about 1.19 yards of dirt. Call it a yard and a half if you want to account for settling.
A yard is 27 cubic feet Youare covering 256 x 2/12 = 42.67 cu ft So you need 42.67/27 = 1.6 yards
Divide everything by 3.10x20x2/3= 400/3
1 ft = 1/3 yd → 1 cu ft = 1 ft × 1 ft × 1 ft = 1/3 yd × 1/3 yd × 1/3 yd = 1/23 cu yd So work out the volume of your hole by multiplying the dimensions together (ft × ft × ft) and divide the result by 27 to get the volume in cu yards, ie: volume in cubic yards = (ft × ft × ft) ÷ 27
6 cubic yards of dirt will cover 70 sq ft ... 2 ft 3 3/4 inches deep
6 sq. yds
27 cubic feet = 1 cubic yardVolume = (14-ft x 14-ft x 1-ft) = 196 cubic feet = 7.26 cubic yards (rounded)
You need 100 cubic yards for every 3-ft deep you want to spread 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)
16 ft * 47 ft * 4 inches =16/3 yards * 47/3 yards * 4/36 yards = 9.3 yards approx.
