An undisturbed sample of sand has a dry weight of 4.20 lb and occupies a volume of 0.038 ft3. The soil solids have a specific gravity of 2.75. Laboratory tests performed to determine the maximum and minimum densities indicate void ratios of 0.42 at the maximum density and 0.92 at the minimum density. Compute the relative density of this material.
