Problem $1$:

A soil sample has a moist unit weight ${}_m=128l\frac{b}{f}{t}^3$ and a void ratio $e=0\mathrm{.}40.$ Assume the specific

gravity $(G_s)$ of the soil particles is $2\mathrm{.}65.$ Determine the dry unit weight $({}_d),$ porosity $(n),$ water

content $(w),$ and saturated unit weight $({}_{\text{s}\text{a}\text{t}})$ of the soil.
