A hexahedron is a polyhedron with 6 faces. In simple words, we can say that a hexahedron is a three-dimensional figure that has six faces. Some of its common examples are cube, cuboid, parallelepiped, Quadrilateral frustum, etc. A cube is a regular hexahedron that has all faces as equal squares with three squares meeting at each vertex. A cube is also called a hexahedron because it is a polyhedron with 6 (hexa-means 6) faces. Cubes make nice 6-sided dice , because they are regular in shape, and each face is the same size. In fact, you can make fair dice using all of the Platonic Solids.16-may-2017 - How to Make a Cube out of Cardboard. A cube is a polyhedron with six square faces.

A rectangular prism is a polyhedron with bases made of rectangles connecting each other. Since a cube has two rectangles connected each side, it's a rectangular prism. A platonic solid is a 3D shape where each face is the same as a regular polygon and has the same number of faces meeting at each vertex. A regular, convex polyhedron with identical faces made up of congruent convex regular polygons is called a platonic solid. There are 5 different kinds of solids that are named by the number of faces that each solid has. …Other names for a polygonal face include polyhedron side and Euclidean plane tile.

Many common objects in the world around us are in the shape of polyhedrons. The cube is seen in everything from dice to clock-radios; CD cases, and sticks of butter, are in the shape of polyhedrons called parallelpipeds. The pyramids are a type of polyhedron, as are geodesic domes. 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 \(6\cdot 9\), or 54 cm 2. The cube is the Platonic solid composed of six square faces t Platonic solid. In geometry, a Platonic solid is a convex, regular polyhedron in three-dimensional Euclidean space.
