# Menger slicing

Geometry Level 3

How good are your visualization skills?

The above shape is called a menger sponge.

It's been sliced through the center by a plane perpendicular to the long diagonal.

What type of shape is left on the cross section?

• Since this is a tier two menger sponge $(M_2)$ there will be two different sizes of the same shape.
• Do not consider the big hexagon on the outside, the one you get from slicing a regular cube. Just consider what shape is on the inside of the hexagon.
