The specific gravity of a soil is 2.60. The soil is at 50% degree of saturation with a water content of 15%. The void ratio of the soil is 

An uncompacted heap of soil has a volume of 10000 m\(^3\) and void ratio of 1. If the soil is compacted to a volume of 7500 m\(^3\), then the corresponding void ratio of the compacted soil is \(\underline{\hspace{2cm}}\) (round off to one decimal place).
A partially-saturated soil sample has natural moisture content of 25% and bulk unit weight of 18.5 kN/m³. The specific gravity of soil solids is 2.65 and unit weight of water is 9.81 kN/m³. The unit weight of the soil sample on full saturation is
