Soil is excavated from a borrow to construct an embankment with a net volume of 50,000 cy. This is performed by compacting 12-in layers of the soil to a dry weight of 110 pcf at a moisture content of 18%. The unit weight of soil in the borrow is 120 pcf with a water content ratio of 15.4%. What is the volume of the required soil excavated in the borrow pit?
