To answer this question we will use the following diagram as a reference:

Therefore the surface area of the given solid is:


\begin{gathered} SA=2(4cm*1cm)+2(1cm\operatorname{*}1cm)+2(1cm\operatorname{*}4cm)+2(4cm\operatorname{*}1cm)+1cm\operatorname{*}4cm \\ +3cm\operatorname{*}4cm+4cm\operatorname{*}4cm. \end{gathered}

Simplifying the above result we get:


\begin{gathered} SA=8cm^2+2cm^2+8cm^2+8cm^2+4cm^2+12cm^2+16cm^2 \\ =58cm^2 \end{gathered}

Answer: Option B.
