The $$chunk density$$ method is often used to determine the unit weight $($and other necessary

information$)$ of a specimen of irregular shape, especially of friable samples. The specimen at its

natural water content is $(1)$ weighed, $(2)$ painted with a thick coat of wax or paraffin $($to prevent

water from entering the pores$),(3)$ weighed again $($Wt $+$ Wwax$),$ and $(4)$ weighed in water $($to get

the volume of the sample $+$ wax coating $$ remember Archimedes?$).$ Finally, the natural water

content of the specimen is determined. A specimen of silty sand is treated this way to obtain the

$$chunk density.$$ From the information given below, determine the $($a$)$ wet density, $($b$)$ dry density,

$($c$)$ void ratio, and $($d$)$ degree of saturation of the sample.
