Soil volume calculator
Estimate loose soil and whole bags for a rectangular area.
A clear answer. Here’s how.
Volume = length × width × depth, converting centimetres to metres. Converts cubic metres to litres, adds your extra-volume allowance and rounds up to whole bags. No settlement or bulk-density value is inferred.
