it is a dodecagon
An isosahedrons has 12 edges many. A cube is one example.
A cube or a cuboid could have 12 edges, 8 vertices, and 6 faces.
Dodecagon Dodeca = 12, gon = sides
Pick any edge. Measure its length. Multiply its length by 12.
If you mean 6 faces and 12 edges then a cube would fit the given description which also has 8 vertices.
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.
