To determine the number of faces in a triangular prism, you need to understand the properties and geometry of a prism.

A prism is a three-dimensional shape that has two identical and congruent polygonal bases connected by a set of rectangular faces. In the case of a triangular prism, the two bases are triangles.

A triangular prism consists of two triangular bases and three rectangular faces connecting the corresponding sides of the bases.

To find the number of faces, you can count the total number of individual faces on the triangular prism.

In a triangular prism, there are two triangular bases and three rectangular faces. This gives us a total of 2 (triangular bases) + 3 (rectangular faces) = 5 faces.

Therefore, the correct answer is 5.
