How many square feet can the 20 ton dump truck hold?
Sand packing density is generally around 1.6, but also is a sand about 1.6 tons, your car load of 20 tons, 20/1.6=12.5, so in the case of overweight, can hold about 12.5 cubic meters of sand, earth would be almost this number.
Soil density is about 2.6, but the bulk density should not be so high, how many did not find out, here in order to sand as a reference
