Quite a bit
3dFace - Creates a three-sided or four-sided surface in 3D space.

Mesh - A mesh model consists of vertices, edges, and faces that use polygonal representation, including triangles and quadrilaterals, to define a 3D shape. Unlike solid models, mesh has no mass properties. However, as with 3D solids, you can create primitive mesh forms such as boxes, cones, and pyramids.

Surface
A surface is a 3D object that is an infinitely thin shell. There are 2 types of surfaces: procedural and NURBS.
Procedural surfaces can be associative, maintaining relationships with other objects so that they can be manipulated as a group.
NURBS surfaces are not associative. Instead, they have control vertices that allow you to sculpt shapes in a more natural way.

Solid - A solid is a 3D object that has mass

A 3d mesh can be more 4 points in a Pface. Polyface mesh from 3D faces..
