Formule

## How to Calculate Concrete for a Slab ### Formula **Volume (cu ft) = Length (ft) x Width (ft) x Thickness (ft)** **Volume (cu yd) = Volume (cu ft) / 27** First convert thickness from inches to feet by dividing by 12. Standard slab thicknesses are 4 inches for patios and walkways, 4-6 inches for driveways, and 6-8 inches for heavy-duty applications.

Exemple Résolu

A patio slab measuring 20 ft by 12 ft with a 4-inch thickness.

  1. 01Convert thickness: 4 inches / 12 = 0.333 ft
  2. 02Volume = 20 × 12 × 0.333 = 80 cu ft
  3. 03Cubic yards = 80 / 27 = 2.96 cu yd
  4. 04With 10% waste = 2.96 × 1.10 = 3.26 cu yd
  5. 05Order 3.5 cubic yards from the concrete plant.
