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.

What is the relationship among the vertices's faces and edges of polyhedrons?
If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
What is a shape that has equal number of faces equal number edges and equal number of vertices?
A sphere- there are no faces, edges or vertices
What is the number of faces edges and vertices of a pentagonal prism?
It has 7 faces, 15 edges and 10 vertices
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 faces and vertices does a cube have?
It has 14 Faces, 24 Edges, and 12 Vertices
What are the names and faces and vertices and edges of a decahedron?
They do not normally have names!
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.
What is the relationship among the vertices's faces and edges of polyhedrons?
If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
What is a shape that has equal number of faces equal number edges and equal number of vertices?

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 is the total number of sides of the faces related to the number of edges?
Faces + Vertices = Edges + 2
Which 3d shape has the same number of edges vertices and faces?
Sphere ( 0 faces , 0 edges , 0 vertices )
What is the name of a shape that has 5 faces 8 edges 6 vertices?
There is not a polyhedron with the given number of faces, edges and vertices.
What 2 3d shapes have the same number of edges vertices and faces?
A cube and a regular octahedron have the same number of edges, vertices, and faces. Both have 12 edges, 8 vertices, and 6 faces.
What is the number of faces vertices and edges of a rectangular prism and a rectangular pyramid?
for any prism , number of ___ + number of vertices = number of edges + ___
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).
