20 vertices.
There are 30 edges on a decagonal prism.
19 * * * * * Actually it is 30 edges. Ten around each of the decagonal faces, and ten more connecting the corresponding vertices of the two decagons.
i think there is 12 faces are in the decagonal prism this is mhel a decagonal prism has 11 faces
30
It depends on a decagonal what. A decagonal prism has 20 vertices. A decagonal pyramid has 11 vertices.
A decagonal prism has 20 vertices: 10 at each end.
20 vertices.
Vertices: 20 Edges: 30 Faces: 12
12 faces 20 vertices 30 edges
Edges = 30 Faces = 12 Vertices = 20
The question cannot be answered because it makes no sense. "Decagonal" is an adjective, not a noun and the answer will depend on whether the question is about a decagonal pyramid, a decagonal prism or decagonal bipyramid, or something else.
There are 30 edges on a decagonal prism.
A decagonal prism has 12 faces
By definition, a dodecahedron must have twelve faces. So it must be an decagonal prism. Edges = 30 Faces = 12 Vertices = 20
12 faces * * * * * Correct as far as it goes, but incomplete. 20 vertices 30 edges
19 * * * * * Actually it is 30 edges. Ten around each of the decagonal faces, and ten more connecting the corresponding vertices of the two decagons.
