seems to me that such a prism has two triangular bases, and three rectangular lateral faces. Where do you get 9 triangles?
A triangular prism is a three-dimensional solid shape with two triangular bases and three rectangular faces. Each triangular base of a triangular prism has three sides. Therefore, to determine how many triangles make up a triangular prism, you need to count the number of triangular faces on the prism. Since a triangular prism has two triangular bases and three rectangular faces, it has a total of 2 + 3 = 5 triangular faces. Thus, a triangular prism is made up of 5 triangles.
There are a total of nine triangles that make up a triangular prism.
I apologize for the confusion - I made an error in my previous response. A triangular prism has actually 5 faces that are triangles: 2 triangular bases and 3 rectangular lateral faces. Therefore, there are 5 triangles that make up a triangular prism.
