Its main application is in finding the volumes of 3D shapes
A shape is an object with a specific number of sides. Some examples of shapes include circles, squares, triangles, pentagons, and hexagons.
the six main crystals are: cubic hexagonal orthcrhombic(?) monoclinic, tetragonal trilinic
3d+8=2d-7 3d+8-8=2d-7-8 (substract 8 on both side) 3d=2d-15 3d-2d=2d-2d-15 (substract 2d on both side) d=-15
There are infinitely many 3d shapes and many of them do not have specific names.
Cubes, pyramids, cones, and spheres are all 3D shapes.
hello
It is impossible to name and draw ALL 3D shapes - there are infinitely many possibilities.
Polyhedra.
It is not possible to list all 3D shapes since there are an infinite number of them Moreover, their names are not sufficiently systematic to provide an alternative way of enumeration.

3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
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.
There is no special name to distinguish shapes with more than 14 sides from those with 14 or fewer.
