# Wrapping presents on the diagonal

…unity to work with surface area and the Pythagorean Theorem. If students are too young to have worked with the Pythagorean Theorem you can use this representation of each rectangular prism which gives a scale drawing on a grid of the 6 by 6 and 6 by 8 faces. Students can figure out the diagonal length by doing a little scale conversion work. How much wrapping paper does this method save? Should you just use a gift bag?
