Concrete — estimated quantities
- Wet volume
- 3 m³
- Dry volume (× 1.54)
- 4.62 m³
- Cement
- 26 bags · 1,270 kg
- Sand (fine aggregate)
- 1.32 m³ · 46.7 cft

Methodology & formulas used
- Wet volume: Length × Width × Thickness
- Dry volume: Wet volume × 1.54
- Cement: (1/5.5) × dry volume × 1440 kg/m³ × wastage
- Sand / Aggregate: Mix share of dry volume × wastage
* These quantities are approximate and based on standard nominal mixes and common site practice. Actual consumption varies with material quality, workmanship, wastage on site and the specifications in your drawings. Always confirm with your engineer or contractor before ordering.
