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.
Answer
50 bags
To what 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. **

50 pounds covers 0.5 cubic feet. Since the depth is 3 inches, or 1/4 foot, you can cover 0.5/.25 = 2 square feet of area. That is not very much.
a 50 pound bag of gravel will cover approximately 2 to 3 square feet of area to a thickness of 3 to 4 inches.

That would depend on the density of the bags of topsoil.

You need (54,450/number of cubic feet of topsoil in each 40 lb bag) .-- One on-line source we consulted says that the weight of topsoil rangesfrom 50 to 100 pounds per cubic foot.-- Another one says that topsoil is usually estimated to weigh 1 ton per cubic yard(27 cubic feet). That would put it at 74.1 pounds per cubic foot ... right in the middleof the range given by the first source.I can see where this is going, and you're not going to like it . . .-- At 75 pounds per cubic foot, that puts 0.533 cubic foot in one 40-pound bag.-- You would need 102,094 of those bags to do the job !-- Even if the topsoil you get is exceptionally light, sandy, and airy, and a40-pound bag holds a full cubic foot, you still need 54,450 of those.
I think one 80 lb. bag will cover about 4 square feet 1 inch thick
The safest deicer for brick driveways is one pound of magnesium chloride. This is mixed with one pound sand in a bucket and is used to cover 4 square yards of brick driveway.
A pound coin is 22½ mm diameter, while a football pitch is approximately 100 x 40 metres, so 4000 square metres. Each coin fits in a 22½ mm square, which is an area of 0.0225 x 0.0225 square metres. That is .0005 square metres. The ratio of the areas is 4000 / .0005 so that football pitch would take 7.9 million pound coins.
A yard is a unit of length. A pound is a unit of mass. The two units are therefore incompatible.
