Give three real-world examples of rectangular prisms. Then give two real-world examples of triangular prisms. Explain how you know the object you chose represents a prism ...

The rectangular prism is a special type of cuboid called a convex polyhedron, which is characterized by having six flat quadrilateral faces. Its label "prism" is due to its characteristic of having a consistent cross-section across one of its faces. This feature lends itself to the concept that the opposite faces of a rectangular prism are congruent or equal. Another characteristic of the rectangular prism is that all angles in its corners are 90 degrees in measurement.
