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.
length x breadth x height=3d
There are some images at the related links below.
Some examples of 3D shapes with angles include cubes, pyramids, and rectangular prisms.
Some 3D shapes are cones, cubes, pyramids, and cylinders.
they are: ---sided pyramids and triangular prisms and 20 sided 3d shapes
here are some: 2d shapes- square circle triangle Rectangle 3d shapes- cone cuboid cube prism
Some 3D shapes will tessellate as for example a brick wall
cube, cuboid, prism, sphere, cone, pyramid .....
There are a lot more than 4 types. Some simple examples: regular polyhedra, other polyhedra, star shapes, ellipoids (including spheres), toroids (like cycle inner tubes), shapes with two "holes" in them, totally irregular blobby shapes.
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.
