Platonic solid to that of a sphere of the same size (i.e. either the same surface area or the same volume.) The dodecahedron, on the other hand, has the smallest angular defect, the largest vertex solid angle, and it fills out its circumscribed sphere the most. Every polyhedron has a dual (or "polar") polyhedron with faces and vertices interchanged. The dual of every Platonic solid is another Platonic solid, so that we can arrange the five solids into dual pairs. If a polyhedron has Schläfli symbol {"p", "q"}, then its dual has the symbol {"q", "p"}. Indeed, every combinatorial property of one
Solid surface wall cladding, because its seamless properties eliminate gaps and crevices that harbor harmful bacteria. Solid surface is manufactured by mixing acrylic, epoxide or polyester resin with powdered bauxite filler and pigments. The material chemically cures and is heated to 60°C or more. Cured material is then cut in sheets or shapes and sanded on one or both sides depending the brand used. Sometimes the material is brought to 160°C and cooled, to improve its heat resistance. Acrylic-modified polyester solid surface can be mixed one sheet at a time using different formulations, effects and appearances. Acrylic-modified polyester solid surface can be
