A cuboid or a cube has 12 edges, 6 faces and 8 vertices
a hexagonal pyramid
Edges or sides? There are 3D figures with one side and one edge.
A cube or a cuboid (also known as a rectangular prism).
The answer is a sphere.

It depends on the same edges as WHAT!
The REGULAR dodecahedron, formed from 15 pentagonal faces, has 30 edges. But there are a number of other 3-dimensional figures which have 12 faces (sides), with different numbers of edges and vertices.

There are infinitely many spatial figures and it is not possible to give a comprehensive answer. For a partial answer, see the following link. However, the link is concerned only with polyhedra. There are other spatial figures - like spheres and ellipsoid etc.
