Cut a cone into two parts with the same shape and size along the diameter and height of the bottom surface. The result is that the sum of the surface area increases by 60 square decimeters compared to the original one. It is known that the height of the cone is 6 decimeters. Then the original cone What is the volume in cubic decimeters?
将一个圆锥沿底面直径和高切成形状、大小完全一样的两个部分，结果表面积之和比原来增加了60平方分米，已知圆椎的高为6分米，那么原来圆椎体的体积是多少立方分米？
