Their relationship is modelled by the equation F + V = E + 2, where F is the number of faces, V is the number of vertices, and E is the number of edges.
Faces + Vertices = Edges + 2 its easy
The Euler characteristic for simply connected polyhedra isF + V = E + 2 where F = # faces, V = # vertices and E = # edges.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. Your figure is a quadrilateral-based prism.
In a polyhedron, there are edges, faces, and corners. The thing that is similar, or common, between the edges, faces, and corners are the vertices.

Topology.
If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
Faces + Vertices = Edges + 2 its easy

some numbers are the same
In a polyhedron, there are edges, faces, and corners. The thing that is similar, or common, between the edges, faces, and corners are the vertices.
For convex polyhedra it is called the Euler characteristic.This requires that V - E + F = 2where V = number of vertices,E = number of edges andF = number of faces.

Each cube has 6 faces, 12 edges and 8 vertices, so two [unconnected] cubes have 12 faces, 24 edges and 16 vertices (between them).
Faces = 4 Vertices = 4 Edges = 6
