Ah, you just have to compute the n-dimenional gaussian.
IIRC you used something like [math]\exp(k r) = \exp(k_1r_1 + k_2r_2 + k_3r_3) = \exp(k_1r_2) \exp(k_2r_2) \exp(k_3 r_3)[/math] and Fubini to split up the integral into the product of the the integrals along each of the three axis, which were all equal.
