an edge of a polyhedron that is not a base edge
A net is an arrangement of polygons, joined edge-to-edge, that when folded up, form the surface of a polyhedron.
yes it is a polyhedron
no a cuboid is not a polyhedron if it was it would have 9 faces
It is not a regular polyhedron because it has unequal sides
No, they are the faces of the polyhedron.

It is an edge.
A polyhedron as for example a pyramid
EDGE

It is unlikely that the question is about a polyhedron which is a 3-dimensional solid bounded by polygons. The minimum number of edges for a polyhedron is 6: the question appears to suggest just 4.
That would be classified as an edge.
No. It is a semi-regular polyhedron. Explanation. The truncated icosahedron is a polyhedron that can be constructed from an icosahedron with the 12 vertices truncated (cut off) such that one third of each edge is cut off at each of both ends. This creates 12 new pentagon faces, and leaves the original 20 triangle faces as regular hexagons A regular polyhedron is a polyhedron whose faces are congruent regular polygons. The truncated icosahedron is NOT a regular polyhedron, it is a semiregular polyhedron. It is a uniform polyhedron.
