Step 1:

First, let's clarify the properties of a triangular prism: - It has two congruent triangular bases (identical in shape and size). - It has three rectangular sides connecting the corresponding sides of the triangular bases.

Step 2:

- Therefore, a triangular prism has a total of 2 + 3 = $$\boxed{5}$$ faces.
Now, let's count the faces: - There are two triangular faces from the bases. - There are three rectangular faces from the sides.

Step 3:

- Since there are two triangular bases and three rectangular faces, we have 2 × 3 + 3 × 4 = $$\boxed{12}$$ edges.
Next, let's count the edges: - Each triangular base has three edges. - Each rectangular face has four edges.

Step 4:

- Since there are two triangular bases, we have 2 × 3 = $$\boxed{6}$$ vertices.
Finally, let's count the vertices: - Each triangular base has three vertices. - The rectangular faces share vertices with the triangular bases.

Final Answer

- A triangular prism has 5 faces, 12 edges, and 6 vertices.
