Rectangular prism
An octohedron
A solid shape that has 6 faces and 12 edges is a rectangular prism, also known as a cuboid. Each of its faces is a rectangle, and it has a total of 8 vertices. The 12 edges are formed by the intersections of the faces. Other shapes, like the cube, also fit this description but are a specific case of the rectangular prism.
A shape with more than 12 edges is a dodecahedron which has 30 edges

A rectangular prism.
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.
