An edge is the curve formed where two of the planes defining [bordering] the 3D shape meet. It is often a straight line where the planes defining the shape meet but, as in the case of a hemisphere, an edge could be a circular boundary where the flat face meets the curved face.
The special features of 3D shapes are they all are 3D which means they are fat but 2D shapes are flat they can not stand up.

2D shapes and 3D shapes are similar in that they both represent geometric forms, but they differ in dimensions. While 2D shapes have only length and width, such as squares and circles, 3D shapes include depth in addition to length and width, like cubes and spheres. Both types of shapes can be defined by their properties, such as angles and sides for 2D shapes and faces and vertices for 3D shapes. Additionally, 3D shapes can be visualized as the three-dimensional counterparts of their 2D base shapes.
Polygons are 2d shapes whereas polyhedrons are 3d shapes
3D shapes have three dimensions, namely length, breadth and height.
A place where two faces meet is called an edge.
3D shapes have edges, sides, and intersecting points
The special features of 3D shapes are they all are 3D which means they are fat but 2D shapes are flat they can not stand up.

A Hexagon has 6 sides, If you are talking Polygons. If you are talking 3D shapes, then there are a whole bunch of them, including a cube.

3d shapes with six faces are called hexahedra.
Cubes, pyramids, cones, and spheres are all 3D shapes.

Polygons are 2d shapes whereas polyhedrons are 3d shapes
Give vidoes to understand the 2d and 3d shapes clearly
No because 2d shapes are plane such as polygons but example of 3d shapes are: pyramid, cone, cuboid, cylinder, sphere ... etc
