The side and face of a 3-D shape are the same thing, but the side of a 3-D object is not, itself 3-Dimensional.

Possibly a face - or an edge. It would help if the question was properly phrased.
A 3D shape with one curved face is a cylinder. It has a circular base and a curved surface that connects the two bases. The curved face wraps around the side, while the top and bottom faces are flat circles.
A 3D cone has two faces: one circular face at the base and one curved surface that wraps around the side. The base is flat, while the curved surface connects the base to the apex of the cone.
a face.
A sphere
A blob.
They both have a face, not a :) face but a side of a shape is called a face and a 2d and 3d shape both show a face of the shape
Mobius strip
An edge.

To answer this question more details need to be provided. For example one a 3D shape one side is called a face.
A triangle is a 2D object, and faces can only be found on 3D objects.But yes, the bottom line of a triangle is still a side, and the bottom face of a 3D object with a triangular face is still a face.
Possibly a face - or an edge. It would help if the question was properly phrased.
Since a face of a 3d figure is the same as a side, you have two faces sharing a face! The result is lots of coincident faces!
3d horizontal side by side
A place where two faces meet is called an edge.
