Formulas & Bag Calculations
- Rectangular Raised Beds: Length (ft) × Width (ft) × Depth (ft) = Total Cubic Feet
- Round Planters / Cylinders: π × (Diameter ÷ 2)² × Depth (ft) = Total Cubic Feet
- Cubic Yards Conversion: Total Cubic Feet ÷ 27 = Cubic Yards
- Bag Multipliers: Supports 1.0 cu ft, 1.5 cu ft, and 2.0 cu ft retail soil and compost bags.
