$100ft\times\frac{30.48cm}{1ft}\times82ft\times\frac{30.48cm}{1ft}\times0.000005\times\frac{2.54cm}{1in}\approx96.74922586cm^{3}$
$96.74922586cm^{3\times}19.32g/cm^{3}\approx1869.195044g$
$1869.195044g\times\frac{1troyounce}{31.1034768g}\approx60.09601613troyounce$
$1654\times60.09601613\approx99398.81$
