A soil sample has a bulk unit weight of 19.6 kN/m^3 at a water content of 10% and
Gs = 2.7 Determine the void ratio, percentage of air in the voids, and the degree of
saturation of this sample

Answers Given are [ 0.49, 45%, 0.55 (55%)]

I don't know what formulas to use - void ratio is basically the volume of water divided by the volume of solids???

Help will be appreciated greatly.

Thanks
