Quick answer
How Many Bags of Concrete Are in a Yard?
A cubic yard of concrete equals about 60 bags of 60-pound pre-mix or 45 bags of 80-pound pre-mix.
Quick answer
How Many Bags Are in a Pallet of Concrete?
A standard pallet of 80 lb concrete bags holds 42 bags (3,360 lbs). A 60 lb pallet holds 56 bags. A 40 lb pallet holds 80 bags.

An 80 lb bag of concrete makes 0.6 cubic feet of mixed concrete. A 60 lb bag yields 0.45 cu ft; a 40 lb bag, 0.3 cu ft.
Quick answer
How Much Does Concrete Cost?
Ready-mix concrete costs $125–$175 per cubic yard delivered in 2026. Installed (with labor and prep) costs run $8–$12 per square foot for a standard residential slab.
Quick answer
How Many Cinder Blocks (CMU) Are on a Pallet? — Weight, Count & Price
A standard pallet of 8×8×16 cinder blocks (also called concrete blocks, cement blocks, or CMU) holds 90 blocks weighing about 3,000 lb total, priced at $115–$225 in 2026. Smaller 4×8×16 half-blocks come 144 per pallet; jumbo 12×8×16 blocks come 60 per pallet.

A standard 4×4 fence post set in a 10-inch diameter, 30-inch deep hole takes about 1.5 cubic feet of concrete — 1.5 bags of 80 lb or 2 bags of 60 lb pre-mix. Always round up.
Quick answer
How Many Bags of Concrete for a 10×10 Slab?
A 10×10 ft × 4 in slab takes 1.23 cubic yards (33.3 ft³) — 56 bags of 80 lb pre-mix or 74 bags of 60 lb. At this volume, a short-load ready-mix delivery is roughly the same total cost as bagged but saves 8 hours of mixing.

Frequently asked
Use the main Concrete Calculator for any slab, pad, floor, or rectangular pour — it returns cubic yards plus 60 lb / 80 lb bag count for any dimension. Use the Concrete Footing Calculator when you are sizing piers, sonotube pours, or below-frost footings, and the Cinder Block Calculator for CMU walls.
A cubic yard equals roughly 60 bags of 60 lb pre-mix or 45 bags of 80 lb pre-mix. Above 1 yd³ ready-mix delivery is almost always cheaper than bagging — see the breakeven on each calculator.
