I'm assuming 24ft X 24ft 6in thick if so you have 10.67 cubic yards so what you need would be 40lb bags would take 961 60lbs would take 641 and 80lb bags would take 481 most concrete places I think only require atleast two to three yard order so I'd go that route make it easier. I'd call and order 11 cubic yards hope this helps
3.56 Cubic Yards
You will need 3.1 cubic yards or 139 80lb bags. This assumes a waste of about 5% which is typical.
About 24 cubic yards of cement is required for a slab that size.
For a 16' x 24' slab with a depth of 4", you would need a minimum of 4.74 cubic yards.
Volume = 11.85 Cubic Yards.

If the 6 is meant to be inches (= 1/2 ft.) then: 8 ft. x 24 ft. x 1/2 ft. = 96 cu.ft. concrete.

11.852 cubic yards
Assuming a thickness of four inches and allowing about 5% waste, you would need 9.33 cubic yards or about 419 80lb bags.
24 beers in a slab
about 432 cubic inches
12-ft x 12-ft x 2-in = 24 cubic feet = 8/9 of 1 cubic yard
