Does an octahedron have six faces, eight vertices and twelve edges

Does an octahedron have six faces, eight vertices and twelve edges

no
A regular octagon has 10 faces, 16 vertices and 24 edges
A regular octahedron is formed by eight equilateral triangles. It has eight faces, six vertices and twelve edges

A cuboid has 8 vertices and 12 edges; its edges can be divided into several groups, with several edges in each group

The edges of a cuboid can be divided into three groups with four in each group
If a special case in a cuboid has the same length of edges, there will be only one group, that is, twelve edges

What is an object with 6 faces, 8 vertices and 12 edges?
An object with 6 faces, 8 vertices and 12 edges is either a cube or a cuboid. Is that right?

No, it's a hexahedron
