SITUATION $5(21-23)$: A dry sand is placed in a container having a volume of $0\mathrm{.}34f{t}^3.$ The dry weight of sand is $42$ lb $.$ A volume of $0\mathrm{.}056f{t}^3$ of water is carefully added to the container so as not to disturb the condition of the sand. If the specific gravity of the sand is $2\mathrm{.}78,$ Determine the following

$21.$ void ratio

a$.0\mathrm{.}432$

c$.0\mathrm{.}404$

b$.0\mathrm{.}563$

d$.0\mathrm{.}331$

$22.$ degree of saturation

a$.0\mathrm{.}699$

c$.0\mathrm{.}411$

b$.0\mathrm{.}573$

d$.0\mathrm{.}535$

$23.$ dry unit weight at zero air void condition

a$.,138\mathrm{.}45l\frac{b}{f}{t}^3$

c$.129\mathrm{.}67l\frac{b}{f}{t}^3$

b$.,140\mathrm{.}891\frac{b}{f}{t}^3$

d$.143\mathrm{.}34l\frac{b}{f}{t}^3$
