How this was worked out

300 sq ft × 3 in ÷ 12 = 75 cu ft. Divide by the bag size — 75 ÷ 2 = 37.5, rounded up to 38 bags — or by 27 for 2.78 cubic yards.

With bags at $3.65 and bulk at $33.95 a yard plus $75 delivery, bulk pays off from about 4.9 cu yd — about 529 sq ft at 3 in. At 2.78 cu yd you are below it, so bags are cheaper and easier to carry to the beds.
