4. The maximum dry density of a proposed borrow soil was found to be 2.2 Mg/m3, and the optimum water content was 13%. The borrow soil has a natural water content of 10%, a degree of saturation of 50%, and a specific gravity of solids of 2.63. Specifications require the borrow soil to be compacted to 95% of the maximum dry density.(a) How many cubic meters of borrow soil will be required to make one cubic meter of compacted fill at the specified dry density?
