## What Are 3d Objects?

3D shapes are solid shapes or objects that have three dimensions (which are length width and height) as opposed to two-dimensional objects which have only a length and a width. Other important terms associated with 3D geometric shapes are faces edges and vertices. They have depth and so they occupy some volume.
