25' x 4' = 100 sq ft. 100 sq ft x 1' = 100 cu ft. 100 cu ft x 2 = 200 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.
2700 x 4/12 = 900 cu ft 27 cu ft = 1 cu yard 900/27 = 33.33 cu yds
1 ft = 12 in → 1 in = 1/12 ft Volume required to cover is 90 sq ft × 1 in = 90 sq ft × 1/12 ft = 7.5 cu ft → number of bags = 7.5 cu ft ÷ 0.8 cu ft/bag = 9.375 bags → you need to buy 10 bags
36 in = 1 yd3 ft = 1 yd1 sq yd = 1 yd x 1 yd= 3 ft x 3 ft= 9 sq ft→ 256 sq ft x 2 in = (256 ÷ 9) sq yds x (2 ÷ 36) yds= 128/81 cu yds= 147/81 cu yds≈ 1.58 cu yds.

2100 x 1/12= 175 cu ft 175 cu ft/27 cu ft per yard = 6.5 cu yds
1 ft = 12 in → 1 in = 1/12 ft Volume required to cover is 90 sq ft × 1 in = 90 sq ft × 1/12 ft = 7.5 cu ft → number of bags = 7.5 cu ft ÷ 0.8 cu ft/bag = 9.375 bags → you need to buy 10 bags
36 in = 1 yd3 ft = 1 yd1 sq yd = 1 yd x 1 yd= 3 ft x 3 ft= 9 sq ft→ 256 sq ft x 2 in = (256 ÷ 9) sq yds x (2 ÷ 36) yds= 128/81 cu yds= 147/81 cu yds≈ 1.58 cu yds.
Volume required = 95 sq ft * 2 inch = 95 sq ft * 1/6 sq ft = 95/6 cu ft = 15.833... cu ft. So number of bags @5 cu ft reqd = 15.833.../5 = 3.166... bags ie 4 bags.
cu ft = sq ft x ft =216 x 1/3 = 72, so cu yds= 72/33 =8/3
1 yd = 3 ft → 1 sq yd = 1 yd x 1 yd = 3 ft x 3 ft = 9 ft 1 yd = 36 in → volume = 4800 sq ft x 5 in = 4800 ÷ 9 sq yd x 5 ÷ 36 yd = 74 2/27 cu yd ≈ 74.074 cu yd.
18 sq m = 193.75 sq ft = 27900 sq in at 1 inch deep = 27900 cu in = 16.15 cu ft sand weighs 100 lbs/cu ft You need 100 x 16.15 = 1615 pounds or 16.15 cu ft = 0.6 yards
400 sq ft at 1 inch = 400x1/12 cu ft = 33.33 cu ft sand weighs 100 pounds per cu ft 33.33 X 100 = 3333 pounds at 50 lb per bag, that is 3333/50 = 66.7 bags
1 acre = 43,560 sq ft → volume pond (liquid) = 3/4 x 43,560 sq ft x 6 ft = 196,020 cu ft * In UK: 196,020 cu ft ≈ 1,220,976 imp gal * In US: 196,020 cu ft ≈ 1,466,331 US gal
