Jamie put 8 squares together to make rectangle. There are 2 rows of squares. Each row had 4 squares. How many pairs of sides touch each other in the rectangle?



Answer :

I believe the answer is ten pairs...
The two rows each have 3 pairs touching, and the four columns each have 1, which makes 2*3 + 4*1 = 10
it is 10 pairs of sides touch each other in the rectangle
