Question

A soil sample has a mass of 20 g and the volume of the soil sample is 15 cm³. The bulk density of soil is:

• A. 1.1 g/cm³
• B. 1.2 g/cm³
• C. 1.3 g/cm³
• D. 1.4 g/cm³

Hint:

Bulk density helps assess soil compaction, affecting root penetration and water movement.

Answer 1

The Correct Option is B

Step 1: Bulk Density Formula
\[ \text{Bulk Density} = \frac{\text{Mass of Soil}}{\text{Volume of Soil}} \]
Step 2: Substituting Values
\[ \text{Bulk Density} = \frac{20}{15} = 1.2 \text{ g/cm}^3 \]
