To determine which shape could be thought of as being created by stacking congruent polygons, let's analyze the given options:
1. Cone:
A cone has a circular base and tapers smoothly to a point called the apex. It is not formed by stacking congruent polygons.
2. Rectangular Prism:
A rectangular prism is a three-dimensional shape with six faces, all of which are rectangles. If you visualize it, you can think of a rectangular prism as being created by stacking congruent rectangular faces (polygons) on top of each other.
3. Square Pyramid:
A square pyramid has a square base and four triangular faces that meet at a single point (the apex). It is not formed by stacking congruent polygons.
4. Triangular Pyramid:
A triangular pyramid (or tetrahedron) has four triangular faces, one of which is the base, and it is not formed by stacking congruent polygons.
Given these analyses, the shape that could be thought of as being created by stacking congruent polygons is the:
Rectangular Prism
Therefore, the correct answer is 1 (rectangular prism).
