you just divide the denominator by 7 and then add 2
The answer will depend on what is known of the shape. If you know only the number of faces, or only the number of vertices, then you cannot work out the number of edges. If you only know the shapes of the faces you cannot.The answer will depend on what is known of the shape.

sphere
There are an infinite number of 3d shapes with more than 20 faces.
There are any number of shapes without flat faces including: > circle > ellipse > blob
They are faces such that the perpendicular distance between them is the same wherever on either face you measure it.

square and rectangle
pentagonal prism
The number of flat sides on the shape eg the cube has 6 flat faces

No, two dimensional shapes do not have faces

no. a 2d square has only 1 face but a 3d square (cube) has 6 faces.
cube and cuboid
