How to Use the Sand Calculator
This calculator estimates the volume (cubic feet), weight (pounds), and number of 50 lb bags of sand needed for a rectangular area.
- Enter Length (ft) – The length of the area in feet.
- Enter Width (ft) – The width of the area in feet.
- Enter Depth (in) – The depth of sand in inches (automatically converted to feet).
- Enter Sand Density (lb/ft³) – Default is 100 lb/ft³ (typical for dry sand). Adjust if needed.
- Click "Calculate Sand Needed".
Results: Volume (ft³), Weight (lb), and approximate number of 50 lb bags (rounded up).
All inputs must be positive numbers. Use imperial units (feet, inches, lb/ft³).
