Question

What would the cross section perpendicular to the base of the figure below produce? Use the most name of the cross -section. The base of the figure is the bottom 15 * 7 rectangle

Answer 1

We have a prism.

We have many possible cross-section that are perpendicular to the base.

If we have a section that is parallel to the front face, with dimensions 15 * 7, we get the same figure: a rectangle with dimensions 15 * 7.

If we make a section parallel to the other face, a square of 7 * 7, we get a figure that is also a square of 7 * 7.

From the options given, the only shape we can get is a square.

Answer: square.
