If the prism is based on regular decagons and it is a right prism, all 12 faces.
12 faces 20 vertices 30 edges
An decagonal prism.
By definition, a dodecahedron must have twelve faces. So it must be an decagonal prism. Edges = 30 Faces = 12 Vertices = 20
i think there is 12 faces are in the decagonal prism this is mhel a decagonal prism has 11 faces
12
A decagonal prism has 12 faces.
20
It has 2 bases and 12 faces
If the prism is based on regular decagons and it is a right prism, all 12 faces.
12 faces 20 vertices 30 edges
Edges = 30 Faces = 12 Vertices = 20
An decagonal prism.
There are 30 edges on a decagonal prism.
Vertices: 20 Edges: 30 Faces: 12
There is no such word as "deconagnol". If you meant decagonal, then the answer is 12 faces. If you did not mean decagonal then please resubmit using corrected spelling.
