polyhedrons
Cubes and pyramids
Polyhedrons are three-dimensional shapes with flat faces, straight edges, and sharp vertices—cubes, pyramids, and prisms are common examples.
The word is the English plural of polyhedron; the Greek-derived plural polyhedra is also standard, especially in mathematical contexts.
The museum displayed crystalline polyhedrons of various sizes.
