A plane is passed through a parallelepiped, cutting all the lateral edges and forming a right section which is square. If the lateral area of the solid is 216cm^2 and a lateral edge measures 9cm, find the measure of one side of the right section.

$A_L = 4 \times 9x$

$216 = 36x$

$x = 6 ~ \text{ cm}$
