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 sphere and regular solids, but the pyramid, prism, cone and cylinder weren't… (More on Stereometry)
