Question

f + v - e in cuboid​

Answer 1

Step-by-step explanation:

General cuboids

By Euler's formula the numbers of faces F, of vertices V, and of edges E of any convex polyhedron are related by the formula F + V = E + 2. In the case of a cuboid this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboid has 6 faces, 8 vertices, and 12 edges.

Vertices: 8

Faces: 6 rectangles

Dual polyhedron: Rectangular fusil

Edges: 12
