Two-10,000 gallon USTs and one-5,000 gallon UST were removed from a site. The excavation resulted in a tank pit of 60 ft x 30 ft x 18 ft. The excavated soil was stockpiled on site. The total bulk density of soil in situ is 1.8 g/cm3 and that of the soil in the stockpiles is 1.6 g/cm3. Calculate the volume (yd3) and mass (tons) of the excavated soil. The density of water is 62.4 lbs/ft3.
