The in situ moist unit weight of a soil is 16.6 kN/m^3, and the moisture content is 19%. The specific gravity of soil solids is 2.69. This soil is to be excavated and transported to a construction site for use in a compacted fill. If the specification calls for the soil to be compacted to a minimum dry unit weight of 19.5 kN/m^3 at the same moisture content of 19%, how many cubic meters of soil from the excavation site are needed to produce 2500 m^3 of compacted fill
