Known: 1 [yd] = 3 [ft] or 1 = 3 [ft/yd]
Also known: 1 [ft] = 12 [in] or 1 = 12 [in/ft]
The volume
= 70 [ft] * 4 [ft] * 3 [in]
= {70 [ft] / 1} * {4 [ft] / 1} * {3 [in] / 1 / 1 }
= {70 [ft] / 3 [ft/yd]} * {4 [ft] / 3 [ft/yd]} * {3 [in] / 12 [in/ft] / 3 [ft/yd]}
= (70/3) * (4/3) * (1/12) [yd^3]
= 2.593 cubic yards
=====================================
24 cubic feet = 0.89 cubic yards
Three acres three inches deep is 403.33 cubic yards.
6 inches = 1/6 yards. So 70 sq yards * 6 inches = 70*1/6 cubic yards = 11.66... cubic yards.
1.851852 cubic yards
3,456 cubic yd.
24 cubic feet = 0.89 cubic yards
Three acres three inches deep is 403.33 cubic yards.
12*15*.33333= 60 cubic feet. 60 cubic feet/27 cubic feet per cubic yard = 2.222 cubic yards
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.
Approx. 8,15 cubic yards; my recommendation is to use only SI units, not obsolete English units.
6 inches = 1/6 yards. So 70 sq yards * 6 inches = 70*1/6 cubic yards = 11.66... cubic yards.
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
13.1 cubic yards, approx.
1.851852 cubic yards

First, convert the depth to inches by dividing 2 by 12 (0.1667 ft). Next, multiply 31 ft by 21 ft by 0.1667 ft to get cubic feet (108.5 cubic feet). Finally divide 108.5 cubic feet by 27 (the number of cubic feet in a cubic yard) to get your answer (4.02 cubic yards). Hope this helps!
