Unfortunately a hexahedron is an ambiguous term. It means a solid object with six plane faces. But that is not enough to uniquely identify shape:
it could be two triangular pyramids with their bases stuck together (a triangular dipyramid), which has 5 vertices (and 9 edges)
or
it could be a pentagonal pyramid, which has 6 vertices (and 10 edges)
or
it could be a parallelepiped (eg cube), which has 8 vertices (and 12 edges).
i say its 12

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.

How many vertices edges and faces does a decahedron have?
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.
Number of faces and edges and vertices of a decahedron?
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
What are the names and faces and vertices and edges of a decahedron?
They do not normally have names!
How many verticies are on a pentagonal decahedron?
A dodecahedron has 12 equilateral pentagonal faces. From this, it has 30 edges as well as 20 vertices in its shape.
How many edges and vertices does a decahedron have?
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.
How many cornets does a decahedron have?
A decahedron has no cornets.

How many vertices does a decahedron?
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.

How many faces edges vertices does a decahedron have?
A decahedron is a shape with ten plane faces. There are 32,300 topologically distinct configurations. Some of the simpler ones are: pyramid with a nonagon base (Faces = 10, Edges = 18, Vertices = 10) prism with octagonal bases (F = 10, E = 24, V = 16) dipyramid with pentagonal base (F = 10, E = 15, V = 7).
