Question

23. Circle the shape that is NOT possible for a cross section of a cube to take.

equilateral triangle , rectangle , square ,
octagon , rhombus , isosceles

Answer 1

Consider this: How many possible sides can a cross section of a cube have?

I count six faces on a cube, so that would mean you can't have more than six sides.

Answer 2

So octagon because 8 > 6

Answer 3

Right, that would be my guess. I can't find a conceivable way for an 8-sided figure to be drawn as a cross section.
