A soil sample collected with a cylindrical core sampler having height of 15 cm and diameter of 6 cm has a fresh weight of 500 g and oven dry weight of 450 g. Calculate bulk density.

Correct option is C

Bulk density = Dry weight / Volume. Volume = π × (r²) × h = 3.14 × (3)² × 15 = 424.1 cm³. Bulk density = 450 g / 424.1 cm³ = 1.06 g/cm³ (approx). Thus, the correct answer is (c).
