Because the condition for common height is only that it must be a whole number, in the posted answer where we took the max of 29 is but just one of many possible answers. Eg. the common height can also be 28, 27, 26 etc. Therefore producing different remaining water left in the basin for each different case.

Thanks Henry! So my answer is correct. I just don't understand, the height can be any no. < 29cm, why must we use the max. height? Any hint in the question what I missed out?

Ok ok, many thanks!

@Maelyn
No, I am quite sure your understanding is correct. It can be any height < 29 cm.
