Is there a solid shape with 5 faces, 8 edges, and 4 vertices?

Annie,

If you are asking about a convex polygon then the answer is no. There is an expression called Euler's Formula that states

V - E + F = 2

where V is the number of vertices, E is the number of edges and F is the number of faces.

There is a discussion of Euler's Formula in the response, by Walter, to an earlier question.
