3D stands for three dimensional. If a shape has length, width, and depth, then it has three dimensions, thus it is 3D.
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.
It is important to learn and remember the name of 3D shapes. A 19 faced 3d shape is called a nonadecahedron.
Diameter
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.

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.
Cubes, pyramids, cones, and spheres are all 3D shapes.
Polygons are 2d shapes whereas polyhedrons are 3d shapes
3D shapes have three dimensions, namely length, breadth and height.

No because 2d shapes are plane such as polygons but example of 3d shapes are: pyramid, cone, cuboid, cylinder, sphere ... etc
