How do you read 3D shapes?
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 shapes are faces, edges, and vertices. They have depth and so they occupy some volume.

What is a long 3D triangle called?
In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid , is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces.
