You can't estimate that without having a thickness. You have to be able to have an actual volume of space you want to fill up with concrete.
To determine the total number of empty bags needed to pack cookies, you need to know how many cookies you're packing and how many cookies fit in each bag. Once you have the total number of bags required, divide that number by 10 (the number of bags per package) to find out how many packages are needed. For example, if you need 25 bags, you would need 3 packages, since 25 divided by 10 equals 2.5, rounding up to 3 packages.

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

bags of what?
1 50kg bag fill about 2 cubic f. so for 102cu.f. you'll need 51 bags
F = W = ( 20 bags ) ( 50 lbf/bag ) ( 4.4482 N / lbf ) = 444.82 N <---[ Answer ]-------
20 bags. 16 oz are in a pound. 10 X 16 = 160 160/8 = 20
That could be answered if we knew the volume of one 40-lb bag. Bags of leaves, styrofoam, beans, and gold all have vastly different volumes.

To determine how many 80-pound bags of concrete are needed to fill a 55-gallon drum, first calculate the volume of the drum. A 55-gallon drum holds about 7.4 cubic feet (since 1 gallon is approximately 0.133 cubic feet). An 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, you would need approximately 12 to 13 bags of concrete to fill the drum.
