How to typeset dimensions of a box?

Question

I want to typeset something like this: 3.0 × 3.0 × 0.9 mm

How can I do that in LaTeX (using siunitx package)?

So far, I have this:

\num{3.0} × \num{3.0} × \SI{0.9}{\milli\metre}

But probably someone else knows a better solution.

Shouldn't it be 3 x 3 x 0.9 mm^3, since the expression describes a volume, not a length?
@Jake, strictly speaking, you are right. But in this context I was only interested in the length dimensions of a box, and not its volume.

\SI[product-units = single]{2 x 3 x 4}{\milli\metre}

enter image description here

From section 5.11 Numbers with units of the manual.
