Volume calculator.
Find the volume of a rectangular space in cubic yards or cubic metres.
Your dimensions
Measurement schematic, not to scale. Use your own dimensions and product specification.
Use measurements from your plan and properties from your chosen product. Any prefilled values are illustrative.
Volume Calculator Calculated volume: 22.22 yd³ Base area: 600 ft² Inputs Length: 20 ft Width: 30 ft Height / depth: 1 ft Formula: V = L × W × H Assumptions: Volume is the product of three perpendicular dimensions. Units are normalised before multiplication. Only quantities from supplied dimensions and specifications are calculated. No material-property reference values are bundled; obtain product values from the selected supplier's data sheet. Based on supplied measurements and specifications. No design suitability or code compliance is assessed.

How this result becomes a purchase quantity
These are the actual stages returned by this calculation. Stages with the same quantity and unit are shown once. Additional stages are not invented.
- Base area: 600 ft²
- Calculated volume: 22.22 yd³
V = L × W × H
Volume is the product of three perpendicular dimensions. Units are normalised before multiplication.
Use your chosen material specification. Quantity does not confirm design suitability.
