Edges are sides in terms of 2D shapes but they are the place where two sides of a 3D shape meet ie. the sharp edge that runs between corners

edges=sides so: 32 sides -> 32 edges
When you say "sides", do you mean faces or edges? A dodecahedron has 12 faces and 30 edges.
A rectangle has 4 sides, which are also its edges. It has 4 vertices where the sides meet. In terms of faces, a rectangle is a 2-dimensional shape and therefore only has one face, which is the flat surface enclosed by the four sides.
a square pyramid, also known as a 4 sided pyramid has 8 edges There are 4 edges where the triangular sides meet each other, and there are 4 more edges where the 4 triangular sides meet the square base.
Faces + Vertices = Edges + 2
