The image above represents bulk density.

To compute for bulk density, two essential parameters are needed and these parameters are **Mass of the soil (m) **and **Volume of the soil (V).**

The formula for calculating bulk density:

s_{b} = ^{m} / _{V}

Where:

s_{b} = Bulk Density

m = Mass of the Soil

V = Volume of the Soil

Let’s solve an example;

Find the bulk density when the mass of the soil is 24 and the volume of the soil is 6.

This implies that;

m = Mass of the Soil = 24

V = Volume of the Soil = 6

s_{b} = ^{m} / _{V}

s_{b} = ^{24} / _{6}

s_{b} = 4

Therefore, the **bulk density **is **4.**

**Calculating the Mass of the Soil when the Bulk Density and the Volume of the Soil is Given.**

m = s_{b} x V

Where;

m = Mass of the Soil

s_{b} = Bulk Density

V = Volume of the Soil

Let’s solve an example;

Find the mass of the soil when the bulk density is 10 and the volume of the soil is 4.

This implies that;

s_{b} = Bulk Density = 10

V = Volume of the Soil = 4

m = s_{b} x V

m = 10 x 4

m = 40

Therefore, the **mass of the soil ** is **40.**
