Stereometry
Stereometry is a branch of geometry and thus of mathematics . In contrast to plane geometry ( planimetry ), it deals with geometric structures in ( three-dimensional ) space . Instead of stereometry, one also says spatial geometry or spatial geometry .
Stereometry includes, among other things, the calculation of the surface ( area calculation ) or the lateral surface and the volume ( volume calculation ) of simple and composite geometric bodies as well as the stereotomy .
In ancient Greece, stereometry was one of the areas of science that was of outstanding importance. Various well-known thinkers of this time tried to solve the stereometric problem of doubling the cube . Plato calls even in his work The state that the solid geometry in addition to the plane geometry in the scientific preparatory course with be included should.
