ABOUT 43 bags. Dry sand weighs ABOUT 100 lbs per cubic foot- and you need 21.3 cubic feet.
The volume of sand weighs 455x 2/12 *100 pounds per cubic foot = 7600 pounds so you need about 152 bags.
is it 1120 bags x 50 kg= 56,000 kg's
120 inch pounds = 10 foot pounds.
You mean foot pounds, not feet per pound. Work = weight x distance = 500 x 60 =3000 foot - pounds
That depends on the dimensions of the bags. You can't equate weight to area or volume. A 50 pound bag of feathers is a lot bigger than a 50 pound bag of sand.
You have a hole here that is 18.3 cubic yards, not .183. Unless your measurements are incorrect. If the measurements are correct, you will need about 800 bags of 80 lb quickrete. Not very efficient. Why not order ready-mix and save the labor of mixing and transporting to the hole. It will cost you around $2000 for the ready-mix. At $4 to $5 a bag it will cost you more for the quickrete. I really don't think your measurements are correct though: creating a slab 1.5 feet thick is unusual. Perhaps one of those dimensions should be inches (") not feet (').Find the correct number of cubic feet (if not 495 as shown here), and divide by 0.6 -- each 80 pound bag will provide about 6/10ths of a cubic foot of concrete.

A foot-pound is not a pound per foot, it is a pound times a foot. So the units are not the same. The question has no answer. It is like asking how to convert feet to pounds or seconds to inches.
