A core cutter having volume 1000 cm3 weighing 1000 g is used to determine the in-situ density of an embankment. The weight of core cutter full of soil is 2850 g. What is the in-situ density of the soil?

A core cutter having volume 1000 cm3 weighing 1000 g is used to determine the in-situ density of an embankment. The weight of core cutter full of soil is 2850 g. What is the in-situ density of the soil? Correct Answer 1.85 g/cm<sup>3</sup>

Explanation:

Volume of cutter = 1000 cm3

Weight of cutter = 2850 gm, Weight of cutter + soil = 1000 gm

Weight of soil, W = 2850 – 1000 = 1850 gm

∴ Insitu density of soil, (ρ = Mass/Volume)  ρ  = 1850/1000 = 1.85 g/cm3
