Question
![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 \(\delta = 1\). The square of the distance from a typical point \((x, y, z)\) of the wedge to the line \(L: z = 0, y = 3\) is
\[ r^2 = (y - 3)^2 + z^2.\]
Calculate the moment of inertia of the wedge about \(L\).
\[ I_L = \boxed{\phantom{I}} \]
(Simplify your answer. Type an integer or fraction.)

**Diagram Explanation:**
The illustration depicts a 3D wedge with dimensions labeled as \(a\), \(b\), and \(c\). The centroid is marked at the origin \((0, 0, 0)\), with each axis labeled: \(x\), \(y\), and \(z\). The wedge is outlined, and its faces are highlighted in a light blue color to indicate surfaces.
The point \(\left(\frac{a}{2}, \frac{b}{3}, \frac{c}{3}\right)\) indicates a specific point within the wedge, demonstrating the distribution of dimensions relative to the centroid.
The axis \(L\) is not explicitly shown in the diagram, but its position is defined by the condition \(z = 0\) and \(y = 3\), orienting the observer to where the moment of inertia should be calculated.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2b582868-f2aa-4085-9fa2-cf8937be45fe%2Fb3410c7b-3aa2-4ebe-a6ee-0e5319a87cbc%2Fy7hfpim_processed.png&w=3840&q=75)
