One 60 lb bag makes about 0.45 ft³ (manufacturer's published yield). Bags are rounded up.
At 1.36 yd³ (62 × 80 lb bags, 4,960 lb), bags and a small ready-mix load are both reasonable. Ask local suppliers for their minimum load and short-load fee before deciding.
Estimate only, not a quote or engineering advice. Disclaimer
The 60-lb bag is the comfortable middle: light enough for most people to lift into a wheelbarrow, heavy enough that a small slab doesn’t take forever.

Water per bag
QUIKRETE's data sheet for its Concrete Mix gives a starting amount of 4 pt (1.9 L) of water per 60 lb bag, up to about 7 pt (3.3 L). Add water a little at a time; too much makes weaker concrete.
Yields are for standard concrete mix. Fast-setting, high-strength and crack-resistant mixes may yield differently, so check the bag you buy. Other sizes: 40 lb, 50 lb, 80 lb.
