Answer by checkley71(8403) (Show Source): You can put this solution on YOUR website!
THE TRIANGLE FORMED IS 7M FOR THE HYPOTENUSE, .03M (3CM)FOR ONE SIDE AND X FOR THE UNKNOWN SIDE.
7^2=.03^2+X^2
49=.0009+X^2
X^2=49-.0009
X^2=48.9991
X=SQRT48.9991
X=6.9994 METERS LONG
-----------------------------------------------
IF THESE FIGURES ARE CORRECT 7M & 3CM. YOU HAVE NO ROOM TO INSTALL THE INSULATION.
