Imagine a square. Two-dimensional. A square has four sides.
Imagine a cube. Three-dimensional. The sides of the squares that make up the faces of the cube are now considered edges.
An edge is the line along which two surfaces of a solid meet.

I assume you mean "how many".In geometry, a hexagon (from Greek ἕξ hex, 'six') is a polygon with six edges ("sides") and six vertices.
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
A pyramid can only have an even number of edges. A bilateral polygonal solid that does have 13 edges is a heptahedron having 4 triangular sides and two rectangular sides, the edge between the rectangles forming the 13th edge.
A pentagonal pyramid (5 sides and 1 base) has 6 faces, 6 vertices, and 10 edges (5 between the sides and 5 with the base).
