Sandy soil in the borrow pit has unit weights of solids as `25.8 (KN)/M^3`, water content equal to `11%` and bulk unit weight equal to `16.4 (KN)/M^3`. How many cubic meter of compacted fill could be constructed of `3500 M^3` of sand excavated from the borrow pit, if required value of porosity in the compacted fill is `30%`. Also calculate the change in degree of saturation. [2072 Ashwin] [8]

Prove: `gamma_t=(1+w)/(1+e)*G.gamma_w`
