Well, 72GByte in the manufacturer's notation which is decimal.
So your disk has 72 * 10^3^3 (= 72'000'000'000) Bytes.
freeBSD works - like every other OS i know - not decimal but dual.
Therefor the disk has 67.055225 * 2^10^3 (= 72'000'000'000) Bytes.

Here we have our 67GiByte disk without the 2GiByte Swap, and a little
bit of unused space due to Sector 63 thingies.
So da0s1a ends up having 64GiByte of which iirc 8-10% are reserved and
used for filesystem optimizations. Makes 57GiByte available with 3% (or
1.8Gi) being used.

So everything is there, it's just a little math. And yes, it's quite
a pain in the ass, but you will get used to it ;]
