体积是几何体占空间的大小,高中教材介绍了特殊几何体的体积公式,但在实际的很多问题中,不是都代入公式就能解决的,而是先要进行某些灵活的变换才能解答。近年各类考试也重视对这方面知识能力的考查,由于学生对体积的一些性质认识不深透,没有系统总结这类题的解题方法,一时难于 Volume is the size of space occupied by geometry. High school textbooks introduce volume formulas for special geometry. However, in many practical problems, not all formulas can be solved, but some flexible transformations are required to answer. In recent years, all kinds of examinations have also attached importance to the examination of knowledge and ability in this area. Because students do not fully understand the nature of the volume, it is difficult to systematically summarize the methods for solving such problems.
