6 cubic yards of dirt will cover 70 sq ft ... 2 ft 3 3/4 inches deep
806.66 Cubic Yards
Dirt has varying densities, but on average, 18 tons of dirt would fill about 12 cubic yards.
14 cubic feet = 0.518 cubic yards
22.22 cu yd
There are 189 cubic feet in 7 yards of dirt. This can be calculated by multiplying the number of cubic yards by 27, since there are 27 cubic feet in a cubic yard.
A cubic yard of stone that is 4" thick would cover 9 square yards or 81 square feet. If you need to cover 7000 sq. ft., you would need roughly 86.5 cubic yards. That's a lot of rock.
0.69444 cubic yard (rounded)
To calculate the volume of dirt needed to fill the area, you would need to know the depth of the area in yards. If the depth is 3 yards, then you would need 1800 yards of dirt (600 cubic yards รท 3 yards). If the depth is 1 yard, then you would need 600 yards of dirt.
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)
None because it's a hole but 6 cubic yards of dirt will fill it up.
133.33 cubic yards, that's 400 feet
