A sphere
A blob.
An edge.

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
To answer this question more details need to be provided. For example one a 3D shape one side is called a face.
The faces in a 3-D shape (polyhedron, for example) are bordered by edges.
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.
Any one of the plain surfaces of a solid, three-dimensional shape. Also Called -- side
sphere
If you have one flat face and I have one curved face, which one of us is the 3d shape? Anyway, a 3d shape with pne f;at, circular face and one curved face could be: a section of a sphere or a section of an ellipsoid cut by a plane parallel to one of its axes, a section of a paraboloid or a cone. There are probably other shapes.
