1) Describe the 2-dimensional figure that will result when we slice a solid rectangular prism parallel to the end faces. Explain how you know this is true.

2) Describe the 2-dimensional figure that will result when we slice a solid rectangular prism parallel to the base. Explain how you know this is true.

Answer 1

The answer for both of these would be a rectangle.

A rectangular prism has 6 faces, all of which are rectangles. Slicing the prism parallel to any of the faces, whether they are end faces or bases, will result in a rectangular cross-section.
