l * w * d = volume, which is not the same as tonnage, unless you're dealing with water.
For sand, reckon on summat around 1.7 tonnes per cubic metre

which if you buy the bulk bags means 2 tonne bags,not so you have some left over but because they call the bulk bags a tonne but they are nominally 850 kg of sand and plenty of water.
i think only pure water equates to 1 litre = 1kg
