To what depth?
40 pounds of topsoil is about 2 cubic feet, which will cover an area of 12 square feet at 2 inches deep.600 square feet divided by 12 square feet per bag is 50 bags.Answer50 bags
We would have to know how deep you want it. I would start with 6 x 80 pound bags.
How deep? Are you talking about dry mix weight or finished weight? Concrete weighs 150 pounds per cubic foot. So if you have a 6" slab, that's 150# for 2 square feet. For a 4" slab, the same amount will cover 3 square feet. For a 3" slab, 4 square feet. Concrete mix is commonly sold in 80 pound bags. The finished weight is the mix plus the water that gets chemically bound to it. There's a guide on the bag telling how many bags you need for a given area and thickness.

5 and a bit ;)

Two forty pound bags and a carry-on and purse or laptop bag.
According to the related link below; the required amount to cover 1 square yard with 4 inches of concrete is 6.6 60 pounds bags.
Forty five 80 pound bags of cement are needed to make one cubic yard of concrete.
It would take roughly 66 bags to cover a 200 square ft area 2 inches thick
The volume of sand weighs 455x 2/12 *100 pounds per cubic foot = 7600 pounds so you need about 152 bags.

To calculate how many 10-pound bags of powder are needed, first convert the 25,000 square meters to square feet (1 square meter is approximately 10.76 square feet). Then, determine the total amount of powder needed by dividing the square footage by 500 (amount of powder per 500 sq ft). Finally, divide the total amount of powder by 10 (amount per bag) to find the number of 10-pound bags required.
16 bags for every 3 inches deep
You would need 31, 80 pound bags to cover 1 cubic yard at 4 inches deep. If you would like the depth to be 6 inches, 45 bags would be needed.
