To do this Jorge will cut identical squares out of the corners of the cardboard and then fold up the sides. Jorge wants to use this box to store some of his card collection. He calculated that he will need the area of the base of the box to be 100 square inches to fit all the cards he has in mind. What is the length of the sides of the squares Jorge needs to cut out of his original cardboard to get the size of box he wants? Write your answer as a number only. Round your answer to 2 decimal places if necessary.
