The bulk density of the normal soil is

Bulk density is defined as the mass of the many particles of the material divided by the total volume they occupy. It can be defined as the Bulk density of soil is the dry weight of soil per unit volume of the soil.
Most of the rocks have a bulk density of 2.65 gm/cm³ and a medium textured normal soil with about 50% of pore space will have a bulk density of 1.33 gm/cm³.
