In a prism, the number of faces, vertices, and edges are related by the formula F + V - E = 2, known as Euler's formula. For a prism, which has two parallel and congruent faces connected by rectangular faces, the number of faces (F) is equal to the sum of the number of rectangular faces and the two congruent bases. The number of vertices (V) is equal to the number of corners where edges meet, and the number of edges (E) is equal to the sum of the edges around the bases and the edges connecting the corresponding vertices of the bases.

If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
Prisms have n+2 faces, n x2 vertices, and n x3 edges. A pyramid has n+1 faces, n+1 vertices, and n x2 edges. "n" comes from how many edges are on the base shape. Hope this helps!
There are 48 edges on 4 rectangular prisms.
5 vertices and 8 edges.5 vertices and 8 edges.5 vertices and 8 edges.5 vertices and 8 edges.
For a simply connected polyhedra, the Euler characteristic requires that E + 2 = F + V
