You add up all the sides and you should get 5!

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.
An icosidodecahedron has twenty triangular faces and twelve pentagonal faces... so 42 sides, but the sides are not all shaped the same.
Well honey, to find the surface area of a triangular prism, you add the areas of all the individual faces. So, you calculate the area of the two triangular bases and the three rectangular sides, then add them all up. It's as simple as that, darling.
it has four faces
it does not have four it has five look it up people thanks to this i have got all my answers wrong and im doing a test put the correct answer next time sorry if this was rude.
