This calculator determines the volume of material needed based on coverage area and depth. It converts square feet and inches into cubic feet and cubic yards, making it essential for estimating materials like mulch, gravel, sand, topsoil, or stone.
Calculation Formulas:
Volume (ft³) = Area (ft²) × Depth (in) / 12
Volume (yd³) = Volume (ft³) / 27
Coverage per yd³ = (27 × 12) / Depth (in)
