A three-dimensional figure can be obtained by rotating a right-angled triangle around the right-angled side AC. It is known that the length of the rotated side is 12dm, and the length of the other straight side is 10dm. What is the volume of this three-dimensional figure?
将一个直角三角形绕直角边AC旋转一周后可以得到一个立体图形，已知旋转边长12dm，另一条直边是10dm，这个立体图形的体积是多少？
