In mathematics, solid geometry was the traditional name for the geometry of three-dimensional Euclidean space — for practical purposes the kind of space we live in. It was developed following the development of plane geometry. Stereometry deals with the measurements of volumes of various solid figures: cylinder, circular cone, truncated cone, sphere, prisms, blades, wine casks. The Pythagoreans had dealt with the regular solids, but the pyramid, prism, cone and cylinder were not studied un… (More on Stereometry)
