An undisturbed sample of fine sand is tested in the laboratory and found to have a dry mass of 3.23 kg, a total volume of 0.00187 m3and a specific gravity of 2.65. Other laboratory tests are performed to determine the maximum and minimum density for the sand. At the maximum density, it isdetermined that the void ratio is 0.38; at the minimum density the void ratio is 0.85. Determine the relative density of undisturbed sample
