For context, after an in-depth Google search, I asked the question "What was the volume of the Space Shuttle orbiter, not just the crew cabin or cargo bay but the total volume of the entire craft?" on Quora on August 15, 2018, and did not receive a satisfactory answer. Then, I attempted to get an answer by asking a few people with modeling programs and/or scale models online if they could do a volume test, to which they declined. So, after a lot of time and deliberation, I decided to get a StackExchange account and ask it here, where hopefully there are some more knowledgeable folks that could answer it.
Also, if possible, what is the "fluid/vacuum volume" (i.e. that without solid elements) in comparison to the full volume?
I want to know this (and for this information to be easily available) partially in order to find the surface-area-to-volume ratio of a "generic" spaceplane for calculations regarding them. The surface area of the Shuttle Orbiter (at least its TPS—if anyone has better figures that'd be great) is easily available, so what is really needed to produce that figure is the volume.
