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.
3D shapes have three dimensions, namely length, breadth and height.
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
There are infinitely many 3d shapes and many of them do not have specific names.
2d shapes only have length and width, while 3d shapes have length, width and depth.
