So to continue the answer the previous poster made...
Using the 100 pcf average weight for sand, and that there are 27 cubic feet in a yard, then 2 yards is equal to 54 cubic feet and at 100 pcf, the total weight is 5400 lbs, or 2.7 tons.
-------
Sorry, but does PCF not stand for Pound per Cubic Foot? So one yard (at 27 cubic feet) weighs 2700 lbs. (which is 1.35 short tons, or 1.2 metric tons)
2 feet.
V = (1/3)*pi*r2*h where h = 2 ft = 2/3 yards and r = 1.5/2 ft = 1/4 yards So V = 1/3*pi*(1/4)2*2/3 cubic yards = 0.0436 cubic yards.
200 cubic feet or 7.4 cubic yards
137.5 cubic feet or 5.09 cubic yards.
You need10.8/(the number of cubic feet of sand in each bag) bags.
18 ft * 18 ft * 2 inches = 6 yards * 6 yards * 2/36 yards = 2 cubic yards.
1 cubic yard = 27 cubic feet12 x 12 x 2 = 288 cubic feet = 102/3 cubic yards
1.85 cubic yards.
(5 x 6 x 1.5) = 45 cubic feet = (1 and 2/3) cubic yards
133.3 cubic feet
You need 8 yards of sand that is 16 foot wide and 2 inches deep which is a volume of 8 x 16/3 x 2/36 ~= 2.37 cubic yards of sand.
Total coverage area 314.16 sq. feet. depth of 2 inches = 1.94 cu yards answer ... around 2 cu yards
