Two polyhedrons have 18 edges: truncated tetrahedron and hexagonal prism.
a shape that has 9 faces
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
A decagon is a shape that has ten edges. DEC means TEN.
a shape that has 9 faces
there are none
Octagon
A hexagonal prism.
A hexagonal prism
An hexagonal cross-section prism has 8 faces, 18 edges and 12 vertices
It is octagonal prism
An octagonal pyramid
Hexagonal Prism
corn
the shape that has 8 faces , 18 edges , and 12 vertices is simply a hexagonal prism not a pyramid my butt :P
