Moment of Inertia for Curved Cuboid

Hi Physics Forums!

Moment of inertia question for you:
I have a cuboid, like the first one in this link

http://en.wikipedia.org/wiki/List_of_moments_of_inertia

only it is curved around the y (w in pic) axis such that the x (h in pic) axis touches the top and bottom ends of the cuboid and it is a parabolic curve that satisfies the following:
z=r*(1-(x^2)/((c/2)^2))
where r is the distance from the origin to the center of the cuboid and c is the chord length (in the x direction)
I need to find what the moment of inertia components would be, and I'm stumped. Any help would be greatly appreciated.
