Question

Which figure cannot be created from a plane section of a cube?

A triangle

B Square

C octagon

D trapezoid

Answer 1

C). Octagon.

Explanation:

A cube has 6 plane faces. That would mean any plane slice that can intersect at most 6 of those faces, creating a hexagon. Not a single plane figure with more than 6 sides could be created by slicing a cube with a plane.

Therefore the answer is C, octagon.
