Or it could be a hexagonal pyramid.
Or a rectangular dipyramid.
A shape with more than 12 edges is a dodecahedron which has 30 edges
It is a cuboid that has 8 vertices, 12 edges and 6 faces
Cuboid.
Octogon
I do not believe that such a shape exists.
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.
dodecagon
A cube
it is a dodecagon
A cuboid has 12 edges, 6 faces and 8 vertices
It has 12 edges and 6 faces
An isosahedrons has 12 edges many. A cube is one example.
Rectangular prism
A cube or a cuboid could have 12 edges, 8 vertices, and 6 faces.
It is a cuboid that has 8 vertices, 12 edges and 6 faces
