How to Calculate Soil or Mulch Volume?
To determine how much soil or mulch you need, multiply the area of your garden bed by the desired depth.
Volume Calculation Formulas:
- Rectangular Bed: Length (m) × Width (m) × Depth (m) = Volume in m³
- Circular Bed: π × Radius (m)² × Depth (m) = Volume in m³
- Convert to Liters: 1 m³ = 1000 Liters
Why Include a Settling Margin?
Fresh soil settles by 10% to 15% after watering. Adding a small buffer ensures your raised beds remain properly filled over time.
