Calculate Copy result

— Enter dimensions and calculate.

• 20 × 10 ft × 3 in = 50 cu ft ≈ 1.852 cu yd ≈ 1.416 m³
• With 10% waste → order 55 cu ft
• Mass only if you enter density (e.g. lb/cu ft or kg/m³)

Bulk volume estimate. Compaction, settling, and gradation affect real demand. Does not invent densities, truckloads, or pricing.

Method: convert L/W/depth to feet; volume = L×W×D; order = volume×(1+waste%). Show cuft, cuyd (÷27), m³ (×0.028316846592). Mass only if you enter density. Example: 20×10 ft × 3 in = 50 cuft; +10% waste → 55 cuft order. Compaction and gradation affect real demand — not truckload or pricing.
