Total Volume
Volume: Length × Width × Depth (converted to metres). For circles: π × radius² × depth. For triangles: ½ × base × height × depth.
Weight: Volume × material density. Each material type has a specific density (tonnes per cubic metre) based on Australian industry standards.
Bags: Weight in tonnes × 50 (standard 20kg bags). We round up to ensure you have enough material.
Bulka Bags: Volume ÷ 1.0 (standard 1m³ bulka bag). Rounded up for ordering purposes.
