## Homework Statement

Compute the moment of inertia tensor I with respect to the origin for a cuboid of constant mass density whose edges (of lengths a, b, c) are along the x,y,z-axes, with one corner at the origin.

## The Attempt at a Solution

I get

[tex]I = M \left(

\begin{array}{ccc}

\frac{1}{3} (b^2+c^2) & -\frac{ab}{4} & -\frac{ac}{4}\\

-\frac{ab}{4} & \frac{1}{3} (a^2 + c^2) & -\frac{bc}{4}\\

-\frac{ac}{4} & -\frac{bc}{4} & \frac{1}{3} (a^2 + b^2)

\end{array}

\right)[/tex]

Can this be right?
