Your goal is to design a new shape for a cereal container that will hold the same volume of cereal as a standard cereal box and costs as little as possible to make. Assume that cardboard costs $0.05 per square inch. How cheaply can you package cereal? (Use properties of surface area and volume to improve packaging design.)

Pick between these figures:
(I chose cylinder)
-What would be the pros and cons on using this shape for cereal.

I need help with a starting basically, and how I found the costs of the standard cereal box and a net of a cylinder, including measurements that would be necessary to produce a cereal box.
