Q:

How many edges does a cuboid have?

A:

Quick Answer

A cuboid has 12 edges. A cuboid is a box-like shaped polyhedron that has six rectangular plane faces. A cuboid also has six faces and eight vertices.

Full Answer

Knowing these latter two facts about a cuboid, the number of edges can be calculated with Euler’s polyhedral formula. This formula states that the number of faces (F) plus the number of vertices (V) minus the number of edges (E) equals 2, or F + V - E = 2.

By substituting 6 for V and 8 for V in this equation, it becomes 6 + 8 - E = 2, or 14 - E = 2. From this equation, it is simple to see that E equals 12.

  • Q:

    How many edges does a polyhedron have?

    A:

    The number of edges of any polyhedron can be calculated using the formula: E = V + F - 2, where "E'" denotes the number of edges, "V" indicates the number of vertices and "F" represents the number of faces. It is derived from the famous polyhedral equation formulated by Leonhard Euler, which states that V + F - E = 2.
