Calculate $\backslash (\backslash$mathrm$\{$I$\}\_\{\backslash$mathrm$\{$z$\}\}\backslash )$ for the beam cross$-$section, for $\backslash (\backslash$mathrm$\{$D$\}=102\backslash$mathrm$\{$~mm$\}\backslash )$ and $\backslash (\backslash$mathrm$\{$t$\}=26\backslash$mathrm$\{$~mm$\}\backslash ).$ Give your answer in $\backslash (\backslash$mathrm$\{$mm$\}^\{4\}\backslash ).$

Remember you can avoid using the parallel axis theorem with the appropriate choice of rectangles, but you are welcome to use it if you prefer!

DO NOT use exponential notation for your answer $-$ Canvas is terrible at it$!$ Enter your answer in full, e$.$g$.1,234,567\mathrm{.}89$ The commas are optional.
