Bulk density is a measure of mass per unit volume of rock and may be expressed, for example, as metric tonnes per cubic meter (t/m3) or pounds per cubic foot (lbs/cu ft). Density is determined by measuring the mass of a sample and dividing this by its volume. As a general rule, the dry mass is obtained by drying the sample and then weighing it ...
