Polyhedron Simple and Small Definition

(This is 10th grade math, please don't make it advanced)

A polyhedron is a three-dimensional geometric shape that is made up of flat faces, straight edges, and vertices. It can be defined as a closed solid with flat surfaces that encloses a certain amount of space. A simple polyhedron is one where two faces meet along each edge and all faces are polygons. A small polyhedron is one that can fit entirely within a given space without overlapping or extending beyond its boundaries.

A polyhedron refers to a three-dimensional shape or object with flat faces, straight edges, and sharp corners or vertices. It is made up of polygonal faces, which are two-dimensional shapes with straight sides. These faces intersect at edges, and the edges meet at vertices.

A simple polyhedron is one that does not intersect itself and has a non-empty interior. In other words, it is a solid shape without any holes or self-intersections.

A small polyhedron generally refers to one that has a relatively compact size and can be held or visualized easily. The term "small" may be subjective and can vary depending on the context or specific dimensions of the polyhedron.
