<p>it’s probably less than 1cm.</p>
<p>Also, assuming you have a 7m by 7m room and shelves on too sides of the room, and 6 layers on each side</p>
<p>take away 1m from each side, you have 5X2X6=60m of shelving, and that’s in a relately normal sized room. If you just have, say 1 room with all the files, </p>
<p>say 15x15m</p>
<p>so you have shelves/walking space/shelves/walking space</p>
<p>lets say a shelf takes 50cm, and walking space 1.5m</p>
<p><strong><em>S</em></strong>S<strong><em>S</em></strong>S<strong><em>S</em></strong>S<em>__S</em>_</p>
<p>that’s 7 shelves at ~13m per, if we have 6 layers, that’s 42X13=420+120+6=546m</p>
<p>right?</p>
