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
10 miles per hour = 142/3 feet per second
Concrete is a mixture of sand, gravel, cement, and water. Generally, you have 1 part cement, 2 parts sand, and 3 parts gravel. Sand makes up about 1/4 or 1/3 of a cubic foot. At 100 pounds per cu ft that is about 25-35 pounds.

Dry sand weighs about 100 lbs. per cubic foot.There are 27 cubic feet in a cubic yard, so that would make the weight of dry sand about 2700 lbs. per cubic yard.To see the weight of wet sand and many other common materials, click the "Actual Weight of Sand can be found here:"link below!
Divide by its density.
A 2500 square foot area x 4' deep is 10000 cubic feet. So you need 10,000 cubic feet of sand. Dry sand has a density of 80-100 pounds or so per cubic foot, so that's somewhere between 800,000 and a million pounds of sand.
14,300 pounds. Sand has a density of 100 pounds per cubic foot.
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.
It depends on the moisture content of the sand (wet or dry) but as general rule of thumb there is 1.5 tonne of sand per cubic metre or to answer your question correctly 1500Kg per cube.
50 feet per minute.
5,280 feet per mile.
That depends on the pounds per cubic feet (PCF) of the the sands. Sand will vary from one place to another. Assuming 106.5 pcf, 1 cubic yards (27 cubic feet) would be 1.44 tons, but 2 tons would be the 2 tons recommended order for safety's sake. A like to a sand calulator is attached.
On average, wet sand can weigh around 120-150 pounds per cubic foot. Given that 1 gallon is approximately 0.1337 cubic feet, 55 gallons of wet sand may weigh between 725-910 pounds.
176 feet per minute equates to two miles per hour.
