Answer:
6480kg/m³
Explanation:
Specific gravity is expressed as;
S = density of substance being measured/Density of the reference sample
Reference sample is the saturated soil
Density of the saturated soil = Mass/Volume
Density of the saturated soil = 2400/1
Density of the saturated soil = 2400kg/m³
Given
Specific gravity = 2.70
Get the dry density of the soil
Dry density of the soil = Specific gravity * Density of the saturated soil
Dry density of the soil = 2.70 * 2400
Dry density of the soil = 6480kg/m³
Hence the dry density of the soil is most nearly 6480kg/m³
