100 squares (Posted on 2006-04-30) Difficulty: 2 of 5
What is the fewest straight lines with which you can make exactly 100 squares?

For example with four vertical and five horizontal lines, evenly spaced, 20 squares are formed: twelve 1x1, six 2x2 and two 3x3.

1x1 -- 40
2x2 -- 28
3x3 -- 18
4x4 -- 10
5x5 --   4
