A cube.
Dodecagon Dodeca = 12, gon = sides
A hexagonal pyramid.
A cube has 6 sides 8 verticies and 12 edges
A shape with more than 12 edges is a dodecahedron which has 30 edges
One shape that has 12 edges is a cube. Any cuboid shape in general like a traditional cube or even an oblong can have 12 edges.
A rectangular prism can have 12 edges, but not every shape with 12 edges is a rectangular prism.
It is a cube or a cuboid which also has 12 edges and 8 vertices
dodecagon
A parallelepiped, of which a cube is a special case.
A cube
it is a dodecagon
the shape that has 8 faces , 18 edges , and 12 vertices is simply a hexagonal prism not a pyramid my butt :P
