The in situ moisture content of a soil is 18% and the moist (total) unit weight is 105 pcf. The soil is to be excavated and transported to a construction site for use in a compacted fill. If the specifications call for for the soil to be compacted at a minimum dry unit weight of 103 pcf at the same moisture content of 18%, how many cubic yards of soil of the excavation site are required for each cubic yard of compacted fill? Assume a soil specific gravity of 2.7.
