Question 1122756
<font face="Times New Roman" size="+2">


The original board is 26 cm by 26 plus 10 cm.  Only the 36 cm dimension is divisible by 9, so the pieces have to be 4 X 26, presuming, of course, that you cut the original board with a zero kerf saw -- something that doesn't exist in real life.
