Platonic solid the inradius "r". That is, The following table lists the various radii of the Platonic solids together with their surface area and volume. The overall size is fixed by taking the edge length, "a", to be equal to 2. The constants "φ" and "ξ" in the above are given by Among the Platonic solids, either the dodecahedron or the icosahedron may be seen as the best approximation to the sphere. The icosahedron has the largest number of faces and the largest dihedral angle, it hugs its inscribed sphere the most tightly, and its surface area to volume ratio is closest
Solid surface is priced to compete with natural stone or quartz surfacing. It is available in many colors and patterns. The material can be formed to shape, which makes it appealing to commercial and industrial designers. Specialist fabricators possess the skills and knowledge necessary to provide advice and customer service. Certain high-heat applications (anything above 400 F /200 C) are discouraged, due to the danger of cracking. Because scratches in solid surface appear white to the human eye, most dark colors are not recommended for high use areas. Solid surface Solid surface is a man-made material usually composed of a combination of
