A pyramid.
A shape with 5 faces and 8 edges is a square (or rectangular) pyramid. However, it is important to note that a square pyramid has 5 vertices in total: 4 vertices at the corners of the base.1 vertex at the top (often called the apex). According to Euler’s Formula for polyhedra ($V - E + F = 2$), a shape with 5 faces ($F$) and 8 edges ($E$) must have 5 vertices ($V$) to exist ($5 - 8 + 5 = 2$). Therefore, a standard polyhedron with only one vertex cannot have 5 faces and 8 edges.
No, it has 4 faces and 1 VERTEX
The cone and the pyramid both have a base and a tip. The cone has a circular base and only 2 faces, 1 edge, and 1 vertex. The pyramid can have 4 verticies, 6 edges, and 4 faces; or 5 verticies, 8 edges, and 5 faces.
A triangular prism, which has 6 vertices and 5 faces.
A triangular prism has 6 vertices, 5 faces and 9 edges
3. You need at least three faces. Four faces meeting at a vertex will form a plane (360 deg), 5 or more will make the shape concave (rippled) at that vertex.
A rectangular based pyramid has 5 faces, 8 edges and 5 vertices whch is the plural of vertex.
Edges: 8 Faces: 5 Vertices: 5
A square based pyramid.
I do not believe that there is such a shape.
If a shape has 5 faces, it's a pentagon.
A pyramid has a number of edges and faces that depends on the shape of its base. For a pyramid with an n-sided polygonal base, it has n edges on the base, n edges connecting the apex to each vertex of the base, and a total of n + 1 faces (n triangular faces and 1 base face). For example, a square pyramid (with a square base) has 8 edges and 5 faces.
