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:
In geometry, a decahedron is a polyhedron with ten faces. There are 32300 topologically distinct decahedra and none are regular, so this name is ambiguous.One regular decahedron is an octagonal prism. Along with its 10 faces, it has 16 vertices and 24 edges.
They do not normally have names!
A decahedron has no cornets.
A decahedron has ten faces.
There is no such object. A decahedron is a 3-d object with 10 faces whereas a dodecahedron is a 3-d object with 12 faces. Each of them can have different numbers of edges.
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.

The correct spelling is Dodecahedron and it has 30 edges.* * * * *The correct spelling for a shape with 12 faces is, indeed, dodecahedron. But the question is about a shape with 10 faces, for which the spelling IS correct.Unfortunately, that is as far as we can go. There are many possible configurations for a decahedron and they have different numbers of edges:For example:A nonagon based pyramid: 18 edgesAn octagonal prism : 24 edgesA pentagonal dipyramid: 15 edges.
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

How many sides does a Decahedron Have
A dodecahedron has 12 equilateral pentagonal faces. From this, it has 30 edges as well as 20 vertices in its shape.
A decahedron has ten faces.
There is no such object. A decahedron is a 3-d object with 10 faces whereas a dodecahedron is a 3-d object with 12 faces. Each of them can have different numbers of edges.
It depends on the configuration. Here are some: A nonagon-based pyramid will have 18 edges and 10 vertices; An octagon based prism will have 24 edges and 16 vertices; A pentagon-based dipyramid will have 15 edges and 7 vertices. There are others.
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 edges will depend on which of these - or the other 32,296 decahedra - you have in mind.
