Weight, \(\displaystyle{W}={m}{g}={0.5}{l}{b}{m}\times{30.5}{f}\frac{{t}}{{s}^{{2}}}\times{\left({l}{b}{f}\frac{{s}^{{2}}}{{32.174}}{l}{b}{m}{f}{t}\right)}\)

To find weight from the above

density \(\displaystyle\rho={\frac{{{m}}}{{{V}}}}={\frac{{{\frac{{{0.5}}}{{{32.174}}}}}}{{{0.145}}}}\)

then find density
