lip of the barrel (that will be half the volume).
Q2:
Divide the matzahs into 3 groups of 3 each.
- Take group #1 and group #2 and place them on the balance.
- if one group is lighter then take that group and place one of the three
matzahs on either side of the balance.
- if one is lighter, then you've found it.
- if they are even, then the third matzah is the lighter one.
- If group 1 and group 2 weigh the same, then the lighter one is in group 3.
Place two from that group on the balance, find the lighter one just as above.
