Using Quikrete (available at most building supply stores), each:
80# bag yields approximately 0.60 ft^3 (cubic feet),
60# bag yields approximately 0.45 ft^3,
40# bag yields approximately 0.30 ft^3.
Simply multiply the ft^3 (cubic feet) needed * the yield (listed above), according to the bag size you want or is available.
2.45' * 2.45' * 5" = 2.5 ft^3. Using 80# bags, 2.5 ft^3 * 0.60 ft^3 = 15 bags. As the yields are approximate, I would get 1 bag extra, just in case.
