Calculated from your measurements.
How it's calculated
Volume = length × width × depth × (1 + waste ÷ 100). Mass = volume × density.
Calculations use consistent units for your selected measurements. The waste allowance is applied once to the measured requirement. Whole purchase quantities are rounded up.
What this estimate includes
Enter the density and depth for the same material condition. Compaction factors are not inferred.
Quantity and arithmetic estimates only. Use project specifications for installation and design requirements.
