Covering a unit square

  1. Nov 28, 2006 #1
    Hello,

    A problem from Newman, which I posted at
    http://www.mymathforum.com/POW/POW1.pdf , asks to show that it is
    impossible to cover a unit square with 5 squares whose sides have
    lengths <1/2.


    It is possible to realize such a covering with 7 squares.


    What if we allow us only 6 squares ?


    JS,

    It's possible with 7 squares, as shown here.
