Use Mr. Stadel's height as a comparison. Use the link to to find out Mr. Stadel's height. I've included enough pictures to unveil the dimensions separately or all at the same time (the "depth" pic has all three).

Area[edit] The surface area of a sphere is: Archimedes first derived this formula[citation needed] from the fact that the projection to the lateral surface of a circumscribed cylinder (i.e. the Lambert cylindrical equal-area projection) is area-preserving; it equals the derivative of the formula for the volume with respect to r because the total volume inside a sphere of radius r can be thought of as the summation of the surface area of an infinite number of spherical shells of infinitesimal thickness concentrically stacked inside one another from radius 0 to radius r.


At infinitesimal thickness the discrepancy between the inner and outer surface area of any given shell is infinitesimal, and the elemental volume at radius r is simply the product of the surface area at radius r and the infinitesimal thickness. At any given radius r, the incremental volume (δV) equals the product of the surface area at radius r (A(r)) and the thickness of a shell (δr): Substitute V: Jumbo-giant.jpg (337×319) Jumbo Giant Gumball Machine. 850 Count Vending Gumballs.

Juice Box Geometry

But have you ever noticed that some juice boxes don't seem to have as much juice as others, even when they have a lot of packaging? You might be amazed how much thought goes into designing a juice box. Each manufacturer has carefully calculated how big each side of the box needs to be to hold a certain amount of juice inside and how altering the box's dimensions affects its overall appearance and packaging. Investigating the geometry of juice boxes can reveal how some have more efficient packaging than others. Background Geometry uses math to describe and investigate different points, lines and shapes. A rectangular box, such as a juice box or cereal box, is called a rectangular prism in geometry-speak.
