  6. 18 squares I think because 60 and 60 is 120 and 30 and 30 is 180 divided that by 10 and it is 18.

  7. 18 because the rectangle is 30 X 60 and the square is
    10 X 10. so take the zeros of the 30 and 60 times them.

  8. I think 18 because the squares 10 by 10 and the rectangle is 30 by 30.
