An 80lb bag of concrete you can at your local home improvement store covers about 4 square foot at 2" thick. So you would need about 144 bags of 80lb concrete.
15.21 cubic yards 1369 40lb bags 913 60lb bags and only 685 of the 80lb bags.

Every 80lb concrete bag should be mixed with 4 quarts or 3.7 liters of water. This mixture will allow you to place aproximately .60cu/ft of concrete. There are 27 cu/ft in a cu/yd. The number then becomes .0222 yards per 80lb bag. Therefore 45 bags of 80lb (4000 psi) concrete ready mix will be enough for 1 yard of concrete.
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
