Valid question, and it's one that is answered in the way of old maths text books!
Basically, gold plating has a general 'thickness' to it dependant on the karat of the gold, in this case you would have to know the surface area involved (tricky to work out due to nooks and crannies in the surface, but not impossible) and then you could work out the coating from here.
