Problem # $2$: A sample core from the compacted soil from the above levee that is being constructed:

Sample volume:

$155\mathrm{.}42c{m}^3$

Moist sample weight:

$286\mathrm{.}622g$

OD sample weight:

$258\mathrm{.}381g$

Determine:

$3.$ The bulk density in $\frac{g}{c}{m}^3.$

$4.$ The dry unit weight in pcf$.$

$5.$ The gravimetric moisture content.

$6.$ The porosity.

Do you see any problems with the placement and compaction of the soil? If so$,$ what remedies would you suggest?
