Well, honey, I hate to break it to you, but that solid you're talking about is a triangular prism. It's got 17 faces, 15 edges, and 10 vertices. So, there you have it - a triangular prism strutting its stuff with all those faces, edges, and vertices.
A triangular prism has 5 faces, including one parallel pair; any of the faces might be considered a "base" depending on its orientation.
yes a triangular prism has got 1 perpendicular face, at the base.
You add up all the sides and you should get 5!
Pentagonal (not pentaginal). 7 faces 15 edges 10 vertices
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
