What does polyhedron mean in elementary school?

Start with the definition of a polygon. A polygon is a 2-dimensional (flat) surface all of whose boundaries are straight lines. Then, a polyhedron is a 3-dimensional (solid) object all of whose faces are polygons.

Where did the name octahedron come from?

A polyhedron is closed a 3-dimensional figure whose faces are all polygons. The prefix "octa-" refers to eight and an octahedron is a polyhedron with 8 faces.

A polyhedron is a two-dimensional figure bounded by polygons?

A polyhedron is a three-dimensional figure formed by flat surfaces that are bounded by polygons joining along their sides (the faces of the polyhedron).A circle is not a polygon, but we can say that a circle is the limit of a regular polygon with n sides. It means that if n becomes larger and larger, the polygon shape approaches to a circle. A circle is a two dimensional figure as a polygon is, but a three dimensional figure whose base(s) is/are a circle cannot be called a polyhedron.

What is meant by the word face in terms of platonic solid?

A platonic solid is a special kind of polyhedron. A polyhedron is a 3-D figure whose faces are polygons.In a platonic solid all faces are identical regular polygons. A polyhedron has faces, edges, and vertices. The numbers of each are related by Euler's formula, V+F=E+2
