Find the surface area of a right pyramid whose base is a regular hexagon each side of which is \( 6\,\mathrm{cm} \) and height \( 9\,\mathrm{cm} \) (see the picture).
\( 162\sqrt3\,\mathrm{cm}^2 \)
\( 15\sqrt3\,\mathrm{cm}^2 \)
\( 9\left(\sqrt3+6\sqrt{13}\right)\,\mathrm{cm}^2 \)
\( 117\sqrt3\,\mathrm{cm}^2 \)
