Answer 2

Sketch of a cube with side = 4 in as shown.

The shaded area is perpendicular to the right and left vertical faces of the cube, so the cross section is a square with each side equal to 4 in.

The area of the cross section is

4*4 = 16 in²

The perimeter of the cross section is

4+4+4+4 = 16 in.
