Natural Convection Around a Heated Box?

Does anyone have (or have any sources for) hand calculations to determine the cooling of a heated box in natural convection?

We have thermal software, but want to be able to do ball park hand calculations to ensure that our software is not off in the weeds. We have a small aluminum box, in free air, heated internally. We are interested in the steady state skin temperature of the box.

Right now the thought is to combine 6 plate analyses as an approximation, but I wasn't sure if there was a more specific model we could use.

Any thoughts?

Thanks in advance!
