A frustum of a pyramid has square ends and the squares have sides \( 18\,\mathrm{cm} \) and \( 6\,\mathrm{cm} \) long, respectively. Calculate the surface area of the frustum if the perpendicular distance between its ends is \( 8\,\mathrm{cm} \).
\( 840\,\mathrm{cm}^2 \)
\( 360\,\mathrm{cm}^2 \)
\( 480\,\mathrm{cm}^2 \)
\( 804\,\mathrm{cm}^2 \)
