How many sides does a 100-gon have
3n edges.
3n. n for the n-gon at each end, making 2n; and n along the length.
24 faces. A 23-gon base, and 23 triangles.
A nonagon, sometimes know as a 'nine-gon' colloquially.

3n. n for the n-gon at each end, making 2n; and n along the length.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.

An icosahedron is a polyhedron with 20 faces. The number of vertices and edges is indeterminate because there are many possible configurations.Three examples:A pyramid with a 19-gon base: 20 vertices, 38 edges.A dipyramid with a decagon base: 12 vertices, 30 edges.A prism with 18-gon bases: 36 vertices, 54 edges.An icosahedron is a polyhedron with 20 faces.

It has 20 faces. The number of edges will depend on the exact configuration of the shape. For example, a icosahedron in the form of a prism, with 18-gons as bases, will have 54 edges. On the other hand a pyramid with a 19-gon base will have 38 edges. A bipyramid with a decagon base will have 30 edges. There are very many more possible shapes.
