What are some commonly used containers that have peculiar exact volumes?

121 Views Asked by At

I am doing a project in calculus in which I must calculate the volume of some kind of container. I didn't wish to choose a boring object. So I wanted to examine the options from the extensive mathematical community. What are some common container-type items (such as a soda can or Gatorade bottle) whose exact volume has interesting properties? For example, suppose the object's volume must be derived via an infinite series or involves the constant e. Or suppose the designers of the product chose, for some reason, to make their container have some kind of interesting or peculiar volume property. Ideally I would prefer the container to be easily able to attain or which is commonly used by the public. Please provide what the object is and what it's exact volume formula is.

Any real-world object can be non-boring if you look to find its volume in enough detail.

You can approximate a basketball as a sphere. But what about the shallow channels on the ball? How long are they? How would you approximate the volume they carve out of the sphere? Or all of the little bumps on the ball: How much volume do they add?

Or a can of soup. Yeah, it's mostly cylinder, but you have the seam of the can, and the caps, and the ridges around the circumference.

Etc., etc., ...
