cube
tetrahedron aka triangular pyramid
A pyramid has the same number of faces as vertices. A triangular pyramid has 4. A rectangular pyramid has 5. Check into Euler's Theorems.
It is a cuboid or a cube
No faces, 1 edge, no corners. A circular disk has 1 face, but that is not the same as a circle.
The faces of a cube are all the same shape - a square.

Three pairs.
I dont know the answer............................
The faces of a cube are all the same shape - a square.
One possible pair is a cube and a parallelepiped. Vertices and corners are the same thing!
Opposite faces.
