How many faces, edges and vertices of a triangular prism. A triangular prism has 5 faces, 9 edges, and 6 vertices. To find the number of faces, we know that a triangular prism has 2 triangular faces and 3 rectangular faces, so the total number of faces is 2 + 3 = 5. can you show your work and wrote it like a 7th grader wrote it.
To find the number of faces in a triangular prism, you need to add the number of triangular faces (2) and rectangular faces (3). So, 2 + 3 = 5 faces.
To find the number of edges, you need to count all the edges of the triangular prism. A triangular prism has 3 edges on each triangular face and 4 edges on each rectangular face. So, 3(2) + 4(3) = 6 + 12 = 18 edges.
To find the number of vertices, you need to count all the corners of the triangular prism. A triangular prism has 3 vertices on each triangular face and 4 vertices on each rectangular face. So, 3(2) + 4(3) = 6 + 12 = 18 vertices.
