In theory, if the park's central attraction were geometrically perfect, it would contain 11,520 of these triangles. However, the need for doors and supports caused the designers to flatten out several of its sections. The monolith’s design is based on the geometry of a pentakis dodecahedron. Each face of this 60-sided figure is then subdivided into 16 smaller faces, leaving a 960-sided structure. These facets are further divided into four triangles, which are then separated into three isosceles triangles which come together at a raised point.
As many people surely do not know the 18-story structure’s name, we should probably clarify that also! The sphere is named “Spaceship Earth”, a term originally used by Buckminster Fuller, the man who first developed the structural mathematics of the geodesic dome. In addition to its post-contemporary design, Spaceship Earth derives much of its futuristic look from its silvery facade. Each of its triangular facets is covered in a material called Alucobond, which is two sheets of aluminum laminated to a core of polyethylene plastic.
