立体几何中的体积问题,是各类考试中的一个重点,有关体积的比也经常可见.许多人认为求体积的比和求体积是相同的,在学习中没有注意比较.其实这两类问题还是有区别的,求体积的比应该比求体积更灵活,它不一定需要求出每个几何体的体积,而可以把体积的比看成一整体来加以处理.下面我们来看一看解决和体积比有关问题的思想方法.
The volumetric problem in solid geometry is a key point in all sorts of examinations. The ratio of volume is also often visible. Many people think that the ratio of volume and volume is the same, and there is no attention to comparison in learning. In fact, these two types of problems There is still a difference. The ratio of the volume should be more flexible than the volume. It does not necessarily need to find the volume of each geometry, but the ratio of the volume can be regarded as a whole to be processed. Now let’s take a look at the solution and volume. Than thoughts about the problem.
