Faces=9 Vertices: 9 Edges=16
It has 8 vertices, 12 edges and 6 faces.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 16 edges, 9 vertices
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.

An octagonal pyramid.
Faces: 10 Vertices: 16 Edges: 24
Faces: 10 Vertices: 16 Edges: 24
It has 6 faces, 16 edges, and 8 vertices.
Faces = 9 Vertices = 9 Edges = 16
16 vertices 24 edges 17 faces
There is 16 vertices,10 faces,and 24 edges.
Faces=9 Vertices: 9 Edges=16
An octagonal prism has: 10 faces 16 vertices and 24 edges :)
If the object is a convex polyhedron, then, by Euler's characteristics, it should have 23 faces.
For all polyhedra: vertices + faces = edges + 2 The given fact is: edges = vertices + 10 → vertices + faces = vertices + 10 + 2 → faces = 12
An octagonal prism has: 10 faces 16 vertices and 24 edges :)
