The 3-d equivalent of a polygon is called a polyhedron. A polyhedron can have 4 or more faces. Cutting off a section of the polyhedron near a vertex adds another face. And it adds at least two more vertices (at least three new, but one lost), so you can keep adding faces.

How many faces this a 3d cube have?
Six faces
How many faces do a 3d square have?
A 3D square is surely a cube? Therefore, a cube has 6 faces.
Faces and vertices of all 3D shapes?
There are an infinite number of 3d shapes. For example you can have an infinite number of prisms with ends that are triangular, quadrilateral, or in the shape of any polygon.
What are faces of a congruent regular polygon?
A regular polygon has equal sides and angles. A polygon has a surface area but a polyhedron has many faces as for example a pyramid.
How many faces does a irregular polygon have?
1
What is a 3d polygon with 4 flat faces called?

Euler's rule for a polygon?
The rule applies to POLYHEDRA (3D shapes) not Polygons, which are 2D Faces + Vertices - Edges = 2

What is the shape called in 3d?
A shape in 3D is a polygon. Poly=many and gon=shape.
How many faces does a 3D hexagon have?
a hexagonal prism has 8 faces.
How many faces does a 3D sphere have?
