一、什么是物体的体积? 物体的体积,就是它所占空间部分的大小。为了度量物体的体积,就要预先选择一个单位体积作为标准。如图1所示,若以左边物体为体积单位,则右边物体所占的空间部分是其16倍,我们就说该物体的体积数是16,或说它的体积是16体积单位。通常,我们取棱长为单位长度的正方 What is the volume of an object? The volume of an object is the size of the space it occupies. In order to measure the volume of an object, a unit volume is pre-selected as a standard. As shown in Figure 1, if the object on the left is the volume unit, the space occupied by the object on the right is 16 times. We say that the volume of the object is 16, or its volume is 16 vol units. Usually, we take the square of the length of the unit of length
