Largest Volume for Smallest Surface. Of all the shapes, a sphere has the smallest surface area for a volume. Or put another way it can contain the greatest volume for a fixed surface area. Example: if you blow up a balloon it naturally forms a sphere because it is trying to hold as much air as possible with as small a surface as possible. Total surface area = area A + area B + area C + area D + area E + area F Using the formula for the area of a rectangle, you can see that the area of rectangle A is: A = l · w A = 10 · 5 = 50 square units Similarly, the areas of the other rectangles are inserted back into the equation above.
