Question

A pentagonal prism is cut by a plane perpendicular to the base. What is the shape of the cross section that is formed?

Answer 1

A prism has a flat base and matcing top with straight sides. What will that look like from the side?

Answer 2

Answer:

The shape of the cross section that is formed on this slicing is:

                    A rectangle.

Step-by-step explanation:

A pentagonal prism is a prism in which the two bases of the prism are in the shape of a pentagon and the five  faces are in shape of rectangles.

Now when the slicing of the prism is done by a plane perpendicular to the base then the cross-section so obtained is similar to the face of the prism.

          Hence, the cross-section so obtained is:

                          Rectangle.
