A polyhedra is described as a shape with many faces. For instance, a die is cube that has many square faces. There are some 3-D shapes called space figures. These are 3 dimensional shapes that include buildings, tools and objects that we create. A polyhedron is also a space figure. Some 2 dimensional figures can be transformed into 3 dimensional shapes. For example, you can transform a rectangle into a 3 dimensional shape.
