It has one flat face if its 2 dimensional. It has 6 flat faces if it is 3 dimensional.
tetrahedron 4, hexahedron (cube) 6, octohedron (diamond) 8, dodecahedron 12 and icosahedron 20.
You know how 2-dimensional shapes are flat right? Well 3-dimensional means that it can go to and from you also.
They are closed 3-dimensional shapes with polygonal faces.
They are both 3 dimensional shapes with faces that are polygons.

Bases are faces but faces are not necessarily bases.
They are alike because they are both 3 dimensional. They are different because the cube has 6 flat faces, but the cylinder has only 2 flat faces and one curved face.

No. A sphere is a three dimensional shape which has no polygonal faces. Similarly an ellipsoid, a torus, a paraboloid, hyperboloid etc are 3-D shapes with no polygonal faces.

Polyhedra are 3-dimensional shapes bounded by polygons. Polygons are flat [plane] shapes bounded by straight lines. So a polyhedron cannot have any curved faces.

3-dimensional is not flat, like a cardboard box, while 2-dimensional shape is flat, like a face of a 3-D shape.e.g, a face of a box.
