Q $09(20$ pts$)$ Determine the products of inertia $I_{xy},I_{yz}$ and $I_{xz}$ of the solid. The $x-y-z$ axes are centered at the body's center of gravity with the z $-$axis pointing up$,$ the x $-$axis parallel to the long side of the body and the y $-$axis parallel to the short side and into the paper. The material density is $490lb\frac{m}{f}{t}^3.$ Also, determine the moment of inertia about the z $-$axis, $I_{zz}.$
