Surface area of a polyhedron
WebMar 27, 2024 · The surface area of a polyhedron is the number of square units that covers all the faces of the polyhedron, without any gaps or overlaps. For example, if the faces of a cube each have an area of 9 cm 2, then the surface area of the cube is 6 ⋅ 9, or 54 cm 2.

WebPolyhedron Shape. A three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices is called a polyhedron. The word ‘polyhedron’ originates from two Greek words: poly and hedron. Here, “poly” means many and “hedron” indicates surface. The names of polyhedrons are defined by the number of faces it has. WebThe parts of a polyhedron are classified as faces, edges, and vertices. Polyhedron Faces: The flat surfaces of a polyhedron are termed as its faces, which are basically polygons. Polyhedron Edges: Edges are the line …
