Half a meter per butt? Really?
A:OK, so we all know that butt-size is one of life’s interesting
variables. Obviously not all butts are the same size, but in this
problem that’s not too important. Even if you had a bunch of people
with more generously proportioned butts, you’d still fit more into the
biggest perimeter, so it’s still a useful comparison.
Is 19.6 butts a lot or a little?
One number on its own isn’t enough to choose a hot tub—
you want the MOST possible butt-space for your 6 square
meters of area. You need to tackle the other hot tubs shapes
to find out if they’re better or worse than the square tub.
19 butts or 19.6 butts? I’ve never met anyone with 0.6 of
A:That’s true, you’d really round down to 19. Only whole butts
can get in the tub (unless you count a really skinny one as a 0.6).
That 0.6 gives a little extra room to the 19 folk in there though, so it’s
worth keeping those decimals in case we end up choosing between
two tubs which both have butt counts between 19 and 20.
Work the formula for circle area backward to get the butt count
for the circle shaped hot tub.
