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