A dodecahedron has 12 equilateral pentagonal faces. From this, it has 30 edges as well as 20 vertices in its shape.
A decahedron is a polyhedron with 10 faces. There are several versions of a decahedron, but none of these are regular. By definition, they all have 10 faces. There is the octagonal prism - with 24 edges and 16 vertices, the square anti-prism, with 16 edges and 8 vertices, the square cupola, with 20 edges and 12 vertices, the pentagonal bi-pyramid, with 15 edges and 7 vertices and the augmented pentagonal prism, with 19 edges and 11 vertices. See, for example, http://en.wikipedia.org/wiki/Decahedron
It has five verticies.
In general, any 10-sided polyhedron is called a decahedron. With 10 regular triangles for faces, you may have a pentagonal bipyramid.
A triangular prism has 6 verticies
A triangular prism has an amount of 4 verticies?
There are many possible configurations for a decahedron and they have different numbers of edges: For example: A nonagon based pyramid: 18 edges An octagonal prism : 24 edges A pentagonal dipyramid: 15 edges.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A decahedron has 10 faces, one example is known as the augmented pentagonal prism.
A decahedron has no cornets.

How many sides does a Decahedron Have
A decahedron has ten faces.
A decahedron is a closed 3-D shape with ten polygonal faces. There are 32,300 topologically different decahdra and, since none of these are regular, the term is ambiguous. Some simple decahedra are:nonagon-based pyramidoctagon-based prismsquare antiprismpentagonal dipyramid.The number of vertices will depend on which of these - or the other 32,296 decahedra - you have in mind.
It has five verticies.
There are many such shapes, not just two. Here are some:A nonagonal pyramidAn octagonal prismA square anti-prism (two square faces, with triangles between them)A decahedronA pentagonal bipyramid (two pentagonal pyramids stuck together at their pentagonal faces).Each one is known as a decahedron (plural decahedra).
A cube has eight verticies.
a pyramid has 6 verticies
