The coordinate axes in the figure run through the centroid of a solid wedge parallel to the labeled edges. The wedge has a = 4, b = 3, and c = 9. The solid has constant density 8 = 1. The square of the distance from a typical point (x,y,z) of the wedge to the line L: z = 0, y = 3 is r² = (y - 3)² + z². Calculate the moment of inertia of the wedge about L. LL (Simplify your answer. Type an integer or fraction.) Centroid at (0, 0, 0)
