Verified Mathematical Model & Formulation

Volume (cu yd) = Length (ft) × Width (ft) × Depth (in) / 324
Weight (Tons) = Volume (cu yd) × 1.1 tons/yd³

Calculates geometric volume and converts to cubic yards and weight using standard topsoil density (~2,200 lbs or 1.1 tons per loose cubic yard).

Configurable Parameters & Standard Units

  • Length: (Default: 16 ft)
  • Width: (Default: 4 ft)
  • Depth: (Default: 8 in)

Standard Worked Example & Practical Verification

Scenario: Filling three raised cedar planter beds, each 8 ft long × 4 ft wide × 10 inches deep.

Calculated Solution
3.26 Cubic Yards (approx. 3.6 Tons)

Practical Takeaway: Order a bulk 3.5 cubic yard delivery of blended 50/50 topsoil and compost.
