Question: How many faces, edges and vertices are there in a triangular prism?


Answer: There’s no real “how-to” here – we just need to count them up! Here we’ve been given a diagram, but it always helps to draw one if not so you don’t forget any “hidden” features. There are 5 faces (2 triangles and 3 rectangles), 9 edges, and 6 vertices.
