mheavner Posted February 26, 2006 Report Share Posted February 26, 2006 Thank you everyone!! I will let you all know what the answer was when He gets it back from his teacher. I'm glad someone else is good at math because it's wasn't my best subject. I carry a calulator and use my fingers when I can't find that!! ha ha.

ughaibu Posted March 13, 2006 Report Share Posted March 13, 2006 Make 10 yards equal to 1 unit and the planks 0.9 units. Up-end the planks together and plant them, like a tree, in the ground. The diagonal distance across the moat is root 2, so, as we have 2 planks in the form of a tree we can dig up the root of 2 and over we go.
