>>>>>>>>>>>>>>>>>>>>>>.

So I used Rotational Inertia = mL^2

For x I did: (40)(-4)^2+(30)(5)^2+(40)(-5)^2+(20)(3)^2

After adding these up I have 2570 g*cm^2 which is the wrong answer. Can you please point me in the right direction? thanks!

well, you did the one for rotation about x=0, the y axis, not the x axis. The numbers are correct.

AH! Thank you!!!
