Well, that is a ridiculous waste of space. Back in the day, even Roddenberry said the original Enterprise corridors were only as wide as they were to fit the camera equipment....
I guess that depends on how the ships are actually made out.
With all the deck plans that get produced, the starting assumption is always that the ships are full of horizontally laid out decks, and each deck is filled with lots and lots and LOTS of little rooms, like a very wide skyscraper.
Given the populations these ships all seem to have, is it *this* that's very wasteful? There was a video shared on another thread recently that estimated the habitable decks of the Enterprise-D as 827000m2. That equates to nearly 83Ha, or more than 200 acres. (WolframAlpha equates it to nearly twice the size of Vatican City).
I work in housing development in the UK. A typical medium-to-low-density development (so all 2-storey, a mix of 2, 3, and 4, bed houses) work get plotted at about 13 or 14 houses per hectare. A higher-density scheme (predominately apartments, some houses; so more likely to ) would typically be about 50 dwellings per hectare. Those figures account for roads, parking, playgrounds etc.
Multiplying the figures together, that would give 1,079 to 1,162 dwellings at low density, or 4,150 at the higher density. The ONS report for 2020 gives the average family size as 2.4. Suggesting a population of 2590, 2789, or 9960, respectively.
Even the lowest of these are many times the 1,012 population of the Enterprise-D as repeatedly stated on screen.
Would a better understanding of the internal arrangement of the Enterprise to be a series of rooms, or more likely collections of rooms that are "floating" within the frame formed by the hull. In that context, would the turboshaft network as depicted in Discovery make more sense, and be "less wasteful" for a perspective of not using unnecessary materials?
