There is a triangular prism and a cube. The base of the triangular prism is an equilateral triangle. The side length is exactly equal to the length of the face diagonal of the cube. The height of the triangular prism is exactly equal to the length of the body diagonal of the cube. If the edge length of the cube is 6. What is the volume of the triangular prism?
有一个三棱柱和一个正方体，三棱柱的底面是一个等边三角形，边长恰好等于正方体的面对角线长度，三棱柱的高恰好等于正方体的体对角线长度，如果正方体的棱长为6，那么三棱柱的体积为多少？
