The maths behind it
This tool uses Volume = length × width × depth, plus wastage. Weight = volume × density. Loose dry sand is about 1,600 kg/m³. Every intermediate value is shown on screen, so the result can be checked by hand.
Sand is sold by weight in some places and by volume in others, and the two only agree if you know the density. Damp sand bulks up and delivers less material per cubic metre than dry.
