Cubes, pyramids, cones, and spheres are all 3D shapes.
Give vidoes to understand the 2d and 3d shapes clearly
There are infinitely many 3d shapes and many of them do not have specific names.
There are infinitely many shapes that do.
A place where two faces meet is called an edge.
3d shapes with six faces are called hexahedra.
They are called Enneahedrons or nonahedrons.
It is important to learn and remember the name of 3D shapes. A 19 faced 3d shape is called a nonadecahedron.
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.

Cubes, pyramids, cones, and spheres are all 3D shapes.
3D shapes have three dimensions, namely length, breadth and height.
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
