Question

Dodecahedron has 30 edges. How many vertices does it have?

Answer 1

regular dodecahedron has 12 faces and 20 vertices, whereas a regular icosahedron has 20 faces and 12 vertices. Both have 30 edges.

Answer 2

Answer:

The number of vertices are 20.

Step-by-step explanation:

Given : Dodecahedron has 30 edges.

To find : How many vertices does it have?

Solution :

A regular dodecahedron or pentagonal dodecahedron is a dodecahedron that is regular.

It is composed of twelve regular pentagonal faces, three meeting at each vertex.

It is one of the five Platonic solids.

It has 12 faces, 20 vertices, 30 edges, and 160 diagonals.

Refer the attached figure below.

Therefore, The number of vertices are 20.
