You must be joking!
About 478,567,990.765 cubic miles
14,300 pounds. Sand has a density of 100 pounds per cubic foot.
The weight of one cubic foot of sand can vary depending on the type and density of the sand. On average, one cubic foot of sand weighs between 90-110 pounds, which is equivalent to approximately 40-50 kilograms.
0ne half cubic foot. One cubic foot is 100 pounds
Dry sand has a density of 100 pounds/cubic foot 1 ton = 2000 pounds 2000 pounds / 100 pounds/cubic foot = 20 cubic foot 20 cubic foot / 27 = 0.74 cubic yard So 1 ton is about 3/4 of a cubic yard
It depends on the height!
I'll use the density of dry, packed sand, which is 100 lbs per cubic foot, 50/100 is 2 50 lb bags of sand
1 cubic foot=100 lbs of sand 1728 cubic in.=100 lbs of sand 864 cubic in.= 50 lbs of sand 432 cubic in.= 25 lbs of sand and so on and so on
It depends on the density of the M sand. Assuming the density is around 100 lbs per cubic foot, one ton of M sand would be roughly 20 cubic feet.
Your patio is (8x8)/6in = 10.66 cubic foot. The sand comes in 50 lb bags that cover 0.5 cubic foot so you will need 21.33 bags (round up to 22 or down to 21)
At 12 inch per foot that is 3.14x30x30*2/12/4 = 117.75 cubic feet of sand at 100 pounds per cubic foot = 11,775 pounds (5.88 tons). Since a yard is 27 cubic feet that is 117.75/27 = 4.4 yards
An area 10 foot x 10 foot is 100 square feet. 100 cubic feet of sand would cover it with a one foot deep layer of sand. If the sand needs to be 6 inches deep, then 50 cubic feet are be needed, or 25 cubic feet if the sand is to be 3 inches thick.
