In a prism, the number of edges is always twice the number of faces, minus two. This is because a prism has two parallel bases (faces) and additional rectangular faces connecting them, resulting in more edges. Specifically, if a prism has ( n ) faces, it will have ( 3n - 6 ) edges, confirming this relationship. Thus, for every face added, there are generally two more edges created.
A cube has 6 faces. The number of faces, alone, is not sufficient to figure out the number of edges. For example, a cube has 12 edges. A pentagonal pyramid also has 6 faces, but it has 10 edges.
A polyhedron that has twice as many edges as faces is known as a triangular prism. In a triangular prism, there are 5 faces (two triangular bases and three rectangular lateral faces) and 9 edges. This means the number of edges (9) is indeed twice the number of faces (5), satisfying the condition of having twice as many edges as faces.
4 faces. 4 vertices. 6 edges.
The answer will depend on what is known of the shape. If you know only the number of faces, or only the number of vertices, then you cannot work out the number of edges. If you only know the shapes of the faces you cannot.The answer will depend on what is known of the shape.

10 number of faces +2 gives you the number of edges
they are congruently uneven evenly
Faces + Vertices = Edges + 2
No, it is not. A cube has 12 edges and 6 faces.
If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
there are 5 faces and 6 edges
A sphere- there are no faces, edges or vertices

A triangular prism has 5 faces, 9 edges and 6 vertices
It has 7 faces, 15 edges and 10 vertices
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.
