正方体是长宽高等长的一个三维物体。这意味着要计算正方体体积只需求出其中一条边的立方积即可。以下为计算方法。

  1. How.com.vn 中文: Step 1 量度正方体某一边的边长
    如果您已经知道正方体的任一边长,请进入下一步骤。否则,用尺子量度正方体的某一条边。这里假设要计算的正方体边长为2厘米。
  2. How.com.vn 中文: Step 2 计算边长的立方积
    ,即对边长进行立方运算。正方形的体积等于底面积乘以高,而底面积等于长乘以宽,由于正方体长宽高相等,所以正方体体积等于任一边的立方积。在本例中,正方体体积为2 x 2 x 2,或23 = 8.
  3. How.com.vn 中文: Step 3 体积单位也应为长度单位的立方
    因为计算的是三维空间物体的体积,所以单位应是长度单位的立方。由于原长度单位是厘米,因此最终结果是8立方厘米(cm3)。
