Exactly. The computer takes up a certain amount of space within the building, but something of that tech level can't do anything unless you also leave a good bit of space around it for several people to sit (at an attached, and also quite bulky teletype console or card reader and punch machine) and circulate (operating the front panels, feeding in cards, collecting printout, and also doing work around the back... reloading printer paper, opening panels to tinker with the circuit boards on a broken unit or tweak the settings on an underperforming one)... etc. That takes up at LEAST as much. – tahrey Jan 25 '19 at 7:01
