restoring a DC9 restroom... at home

A 15" medicine cabinet was designed to fit between standard 2x4 studs on
16" centers. The blades dropped into the inter-wall space created by those
2x4s. A quick calculation for a medicine cabinet at 5' high, 15" wide,
3.5" deep shows a space of some 3150 cubic inches. Assuming the blades
were about 1" x 2" x 0.005, this gives a blade volume of.01 cubic inches.
You could drop 315,000 blades into the slot before the space filled up. If
you changed blades every other day, you had a little over 1700 years of
capacity.

Good explanation but you forgot to factor in corrosion of those blades. By
the time you reach 1700 years, the first 1200 years of blades would have
corroded to almost nothing. This would give at least another 500-600 worth
of storage. You can calculate out the rest....

Back in the days of carbon steel razor blades, corrosion would reduce the
blades to dust (dust that takes up more room than the uncorroded blade
itself, BTW).

But today's double edged safety razor blade is made from a form of stainless steel, and
doesn't rust.

Have you factored in wall critters making off with some of the blades?
Little mouse blacksmiths working into the the night pounding out swords,
armor, spears...

Except that iron oxide takes up even more space than the iron ....

OMG... there may only be 1000 years of capacity. Time for an emergency AD!

Umm.. I don't think so. Inside the wall (as opposed to exposed to
the elements) there is nothing carrying the corroded material away.
It doesn't simply evaporate.
