As shown, an I$-$beam $($Figure $2)$ has a bottom flange that is $300$mm$60\mathrm{.}0$mm$300$mm$60\mathrm{.}0$mm$,$ a web that is $60\mathrm{.}0$mm$300$mm$60\mathrm{.}0$mm$300$mm$,$ and top flange that is $150$mm$60\mathrm{.}0$mm$150$mm$60\mathrm{.}0$mm$.$ Determine the moment of inertia of the I$-$beam about the horizontal centroidal axis using the parallel$-$axis theorem.
