Calculating Volume and Surface in Three-Dimensional Geometry

WebA three-dimensional shape whose faces are polygons is known as a polyhedron. This term comes from the Greek words poly, which means "many," and hedron, which means "face." So, quite literally, a polyhedron is a three-dimensional object with many faces. The faces of a cube are squares. The faces of a rectangular prism are rectangles. WebLesson 13 Summary. A polyhedron is a three-dimensional figure composed of faces. Each face is a filled-in polygon and meets only one other face along a complete edge. The ends of the edges meet at points that are called vertices. A polyhedron always encloses a three-dimensional region. The plural of polyhedron is polyhedra.
