Let \( ABCDEFA'B'C'D'E'F' \) be a regular hexagonal prism with the base edge length of \( 4\,\mathrm{cm} \) and the height of \( 8\,\mathrm{cm} \). Find the distance between the points \( E' \) and \( C \) (see the picture).
\( 4\sqrt7\,\mathrm{cm} \)
\( 8\sqrt2\,\mathrm{cm} \)
\( 8+4\sqrt3\,\mathrm{cm} \)
\( 16\sqrt7\,\mathrm{cm} \)
