However, boards are normally specified in
board-feet, rather than W/H/L.

How would that look in this case, i.e.
3.5x9.5x120cm? (Or 3.5/9.5/120cm following
your template.)

Hardwoods aren't normally sold as finished boards and may not even be
square (depending of grade[*]) and almost certainly not standard width
and length (thickness is more standardized - listed by multiples of
1/4" but that, too, is nominal thickness). When buying hardwoods, one
measures. ;-) A board-foot is 1" thick, by 12"x12", so one has to
calculate from there to get pricing.

necessarily square)
