Question

which shape could be thought of as being created by stacking congruent polygons?
cone
rectangular prism
square pyramid
triangular pyramid

Explanation:

A rectangular prism has two congruent rectangular bases and can be thought of as stacking congruent rectangles (polygons). A cone has a circular base (not a polygon). Square and triangular pyramids have a single - base and slanted faces that are not formed by simply stacking congruent polygons in the same way as a prism.

Answer:

rectangular prism
