A density test was performed on a soil sample obtained from the field. The sample was contained in $4$ similar containers, each of which had an inside diameter of $2\mathrm{.}43$ inch and was $1\mathrm{.}0-$inch height. The net weight of the soil in the four containers was $1\mathrm{.}35lb.$ Compute:

a$)$ Moist unit weight of the soils. $||$

b$)$ If the dry unit weight is determined as $100pcf,$ and assuming a specific gravity of $2\mathrm{.}62,$ what is the void ratio in these four containers?
