Sorting out knowledge points Geometry

In mathematics, solid geometry is the traditional name for the geometry of 3-dimensional Euclidean space - because in fact this is roughly the space we live in. Generally taken as a follow-up course in plane geometry. Stereometry deals with the measurement of volumes of different shapes: cylinders, cones, frustum, spheres, prisms, wedges, bottle caps, etc. The Pythagoreans had dealt with spheres and regular polyhedra, but pyramids, prisms, cones, and cylinders were little known before the Platonists. Eudoxus established their measurement method, proving that a cone is one-third the volume of a cylinder with equal bases and equal heights, and was probably the first to prove that the volume of a sphere is proportional to the cube of its radius.
