Two polyhedrons have 18 edges: truncated tetrahedron and hexagonal prism.
the edges of a shape are basicly the sides of a shape
a sphere has no edges. a circle has no edges.
A shape with more than 12 edges is a dodecahedron which has 30 edges
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. An octohedron can have 12 to 18 edges.
Two polyhedrons have 18 edges: truncated tetrahedron and hexagonal prism.
there are none
Octagon
A hexagonal prism
A hexagonal prism.
An hexagonal cross-section prism has 8 faces, 18 edges and 12 vertices
Hexagonal Prism
corn
An octagonal pyramid
It is octagonal prism
the shape that has 8 faces , 18 edges , and 12 vertices is simply a hexagonal prism not a pyramid my butt :P
