Weight of A = 3 Cubed = 3 X 3 X 3 = 27
Weight of B = 6 Cubed – 6 X 6 X 6 = 216
We can see that 216 is 8 times as great as 27;
though animal B is only 2 times as long as animal A,
it is 8 times as heavy.
(Note that 2 cubed is 8.)
As for the strengths of their legs:
Strength in A = 3 squared = 3 X 3 = 9
Strength in B = 6 squared = 6 X 6 = 36
