Can or bottle? A can will be the calculation for the surface area of a cylinder which is A=
![2 \pi rh+2 \pi r^{2}](/tpl/images/0401/1972/22aa0.png)
if r is the radius of the circle on the top and bottom of the can and h is the height of the can. A can is basically two circles and a big rectangle. For a bottle I don't know there are too many components and no numbers to solve for that
