How many 80 lb bags of Quickrete are needed to fill 0.183 cubic yards of area. Area is 10' X 1.5' X 33'?

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.
