The answer depends on the thickness of the covering layer.
The answer will depend on the depth of the soil cover.
The answer will depend on the depth to which the substance is applied.
For 1 foot deep, 400 cu ft. For 3 inches deep, 100 cu ft.
It would cover 5 sq. ft. one foot deep, or 60 sq. ft. one inch deep.
360 cu ft or if the "4" is inches, not feet, one twelfth of that, ie 30 cu ft
(2000 sq. ft.) X (1 in.) X (1 ft. / 12 in.) = 167 cu. ft.(167 cu. ft.) X (1 cu. yd. / 27 cu. ft.) = 6.2 cu. yd.Full size pickup truck will hold 2 to 3 cu. yd.Tandem axle box truck will hold 10 cu. yd.
v = 30 x 30x5 = 4500 cu ft
17 sq ft * 3 in = 17*3/12 cubic ft = 4.25 cu ft. So 6 cu ft will cover it.
3.14 x 12 x 12/4 x 30/12 cu ft x 7.5 gallons per cu ft = 2120 gallons
If the units are 30 ft x 30 ft x 4 inches, then you have 30 x 30 x 0.33 ft = 300 cubic feet300 cubic ft/27 cu yds/cu ft = 11.1 cubic yards
12 in = 1 ft ⇒ 60 ft x 100 ft x 4 in = 60 ft x 100 ft x (1 ÷ 12) ft = 500 cu ft Close, but you left out the 4 in (1/12) above. You had it on the left, but you left it out on the right. That makes the correct answer 2000 cu ft.
50 pounds @ 100 pounds / cu ft = 0.5 cu ft = 864 cu ins So : sq root (864 / 2) = 20.785 inches So: will cover a square of 20.785 ins * 20.785 ins ( 1.732 ft * 1.732 ft) 2.999 sq feet area each bag (say 3 sq ft)
