How is rectangular prism alike to rectangular pyramids?

Answer 1

Rectangular prisms have two rectangles at each base. Take four lines and connect the four corners perpendicularly of the two rectangles to make a rectangular prism.

Rectangular pyrimads only have one rectangle base. Draw four lines from the four corners of the rectangle and make those four lines meet at one point.

The way these two are alike is that they both had rectangular bases.
