This activity investigates how you might make squares and pentominoes from Polydron.
If you had 36 cubes, what different cuboids could you make?
You have to use the clues given in the question to find out
who's who in the family, to fill in the family tree and to find out
which of the family members are mathematicians and which are not.
This question does not require any mathematical knowledge but it
does call for logical thinking which is needed to do
In the family tree square boxes indicate males and round boxes
Each set of siblings (brothers and sisters) is in descending
order of age from left to right across the page.
Exactly five of the people represented in the tree are
Unusually for this sort of problem, everyone always tells the

It may help you to know that E is the youngest male in the
