A dodecahedron is a polyhedron with 12 pentagonal faces. Each pentagon has internal angles that sum up to 540 degrees. Therefore, the sum of all the angles in a dodecahedron can be calculated by multiplying 540 degrees by the number of faces, which is 12. This results in a total sum of 6480 degrees.

What is the sum of the interior angles of an dodecahedron?
180 degrees
Does a dodecahedron have parallel faces?
A dodecahedron is a polyhedron with 12 faces, each of which is a regular pentagon. In a dodecahedron, the faces are not parallel to each other. The planes of the faces intersect at various angles, giving the dodecahedron its unique shape and properties.
How much is the sum of all the angles in a right triangle?
The sum of the angles in all triangles (right, isosceles, scalene, and equilateral) in the Euclidean plane is 180 degrees or pi.
What is the sum of the exterior angles of a undecagon?
All polygons, including an undecagon (11-sided figure) have a sum of exterior angles of 360 degrees.
What is the sum of the angles of a 14-gon?
Sum of exterior angles: 360 degrees Sum of interior angles: 2160
