Question says: Start with the square [0,1] x [0,1] and remove the middle square [1/3,2/3] x [1/3,2/3]. Divide the part of the original square that remains into 8 congruent squares each have side of length 1/3:

[0,1/3] x [0,1/3];   [0,1/3] x [1/3,2/3];   [0,1/3] x [2/3,1];    [1/3,2/3] x [2/3,1];   [2/3,1] x [2/3,1];    [2/3,1] x [1/3,2/3];   [2/3,1] x [0,1/3];  [1/3,2/3] x [0,1/3]
