An example would be a cube.

A rectangle is a two-dimensional shape, defined by its length and width. It lies flat on a plane and has no depth, distinguishing it from three-dimensional shapes like cuboids or cubes, which have height in addition to length and width.

A face
the 2 demensional is flat and the 3 demensional shape is like a cube(it is popped out).

2d, or two demensional
No it is NOT a polygon, because polygons reffer to 2-demensional figures, however, a CUBE is three demensional.
3 demensional
Triangle is a shape with three sides.

A six sided polygon means a two demensional shape with six sides. For example a hexagon has 6 sides and a hexagon is a two demensional polygon. CHAPTERDUCK
