The answer depends on the depth to which you wish to cover it.
That would depend on the density of the bags of topsoil.
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
27 1 cu ft bags or 9 3 cu ft bags.
A lot
Almost exactly 2.00 cubic yards for every inch of topsoil depth.
That dependsThat depends upon how deep you wish to cover the area. It also depends upon the moisture content of the soil in the bags. Bagged soil is usually pretty wet, so you're paying for water, to a certain extent. Moist topsoil weighs about 90 pounds per cubic foot, so a 40-pound bag is less than half a cubic foot -- 0.44 cubic foot, to be more exact.So, you're going to need about 34 bags -- FOR EVERY INCH OF DEPTH !! -- to cover the area. If the dirt isn't too wet, you might get away with 30 bags per inch of depth.**Actually a 40lbs bag is closer to .75cf. **
It depends on the size of the bags. There are 20 hundredweights to the to but as health and safety czars do not allow builders to lift that, most bags are now 1/2 a cwt so that will mean 40 bags to the ton.
Insufficient information.You need to know the depth of topsoil you want to cover those 7550 sq ft.By "yards" I assume you mean cubic yards -- a volume measurement.
15.833... [cubic] yards.
20 lbs takes us 0.2 cubic feet; a yard is 27 cubic feet; that would take 27/.2 = 135 bags. That is a lot of bags, with total weight of 2700 pounds
The area of a circle is determined by multiplying the square of its radius by the constant pi. The radius is defined as one half the diameter. The value of pi is 3.14. So, 3.14 * 62 = 113.1 square feet. Since a bag of topsoil covers three square feet, you will need 38 bags, because 113.1 square feet divided by three square feet per bag yields 37.7 bags.
