A soil weights $1483k\frac{g}{?}$ loose, $1839k\frac{g}{?}$ in its natural state, and $2106K\frac{g}{?}$ compacted

a$)$Find the soil load factor$($Lf$)$ and shrinkage factor$($Sf$)$

b$)$ If you want to sign agreement with a dump truck owner for hauling the excavated material with a price of $6$ birr $\frac{?}{m3},$ how much does it cost you to move $2000$Bcm$?$

C$)$ For the Question in B$,$ If you sign agreement to pay per trip$/$biyajo and the rated capacity of the $\frac{d}{?}$ truck is $18$ m $3$ and the fill factor is $0\mathrm{.}9$ how much does it cost you to move $2000$ Bcm $?$ If the price is $\frac{108}{?}$ trip$($biyajo$)$
