10 squares can be drawn in 3 dimensions by constructing
this "chair" using 22 line segments.  Since each line 
segment is 15ft long, the minimum amount of wire needed 
is 22x15 or 330 ft.  3 line segments cannot be seen 
in the drawing as they are back behind the bottom cube.



If this must be done in 2 dimensions I think the minimum 
number of segments is 27, and 27x15 or 405 ft. of fencing would
be needed.
