I have been working on these two problems for a long time and i just can't quite figure out how to do them.
1. the postal service will accept a cylindrical package with a maximum combined length and girth (perimeter of the cross-section) of 108 inches. find the dimensions of the package of maximum volume that can be sent.
2.a kite kit, including everything needed to build a kite, sells for $46.00 at the store. the kite kit contains 6 pieces of wood for the frame, material required to cover the frame and make a custom tail, and illustrated assemble instructions. the kite frame kit comes with 4 precut pieces that form the border of the kite and 2 cross pieces that must be cut to the desired size before assembly. how long should each of the 2 crosspieces be cut to maximize the area of the kite?
** the kite is a rhombus and the 2 longer sides are 12 and the 2 shorter sides are 5
