体积计算是高考的重点,它涉及立体几何的各种思想方法、所有的定理公式,既要灵活运用几何体的点、线、面之间的位置关系,又要灵活运用一些解题技巧,如等体积转换、分割、补形、换底等技巧,这些方法、技巧的指导思想都是化残缺为完整,化陌生为熟悉,而后解之. Volume calculation is the focus of college entrance examination, which involves a variety of ways of thinking of three-dimensional geometry, all of the theorem formula, it is necessary to make flexible use of the geometry of the point, line, the relationship between the surface, but also flexible use of some problem solving skills, such as Volume conversion, segmentation, fill the shape, for the bottom of the skills such as these methods, the guiding principle of the skills are incomplete incomplete, unfamiliar as a familiar, and then solution.
