If we take the area of that circle ( \(A = \pi r^2 \) ) and extend it up through the height h, then our volume for the can would be: The area of the sides is a rectangular shape with height h and width equal to the circumference of the circle top/bottom. \(SA = b^2+ 2bh \) where \(h\) is the diagonal height of the triangle, not the height to the tip of the pyramid.
