in a construction project, the field moist unit weight was $18\mathrm{.}08k\frac{N}{m^3}$ at a moisture

content of $8\%.$ If maximum and minimum dry unit weight determined in the

laboratory were $16\mathrm{.}93k\frac{N}{m^3}$ and $14\mathrm{.}46k\frac{N}{m^3},$ respectively, what was the field rel$-$

ative density?
