Moment of inertia of curved cuboid

Moment of inertia of curved cuboid

(OP)
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.

RE: Moment of inertia of curved cuboid

1) math ... integrate the volume ... I = int(y^2*dA)

2) cad ... draw your shape in the cad program of your choice, and as it for properties.
