Truck or bags?

Rule of thumb: over 1 cubic yard, order ready-mix — mixing 40+ bags by hand is a punishment, not a project. Under a yard, bags are fine: an 80 lb bag yields about 0.60 cu ft, a 60 lb bag about 0.45 cu ft.

Always keep the 10% waste factor — uneven ground eats more concrete than you think, and a second truck trip costs far more than an extra bag.
