Depends on what you define as the seashore, as well as what you define as a "shell". Do fragments count? What about the shells of sea urchins, crabs, horseshoe crabs, etc? And how about the shore? Does the intertidal zone count? What about the littoral zone? Also, many shores have layers of sediment stacked on top of each other. How deep can you go and still call it the shore? Depending on your answers, you could be many magnitudes, perhaps even as far off as five magnitudes, off.

Sorry, should have clarified. Only shells that are intact and on the surface to an inch deep. Any kind of shell though

If a 6-pack of Monster got converted into pure energy based on its caloric content, how long could it keep a 60-watt lightbulb on for?

If we took all the energy used by phones in the world in a day, how long could we produce the same power as the Sun (seconds)?

Sanibel is a great place for finding sea shells by the seashore.

### Re: Fermi Questions C

Guess I'll make another question...

What is the sum of all natural numbers (I'm just kidding- who needs zeta function regularization)

Taking the total amount of sugar the USA consumes in a year and converting it into energy, how far could a model TeslaX go?

I'm still kinda new, any feedback would be appreciated.

I'm new too, but here's one estimation that strikes me as maybe being a bit too small.

A single can of Coke has about 40 grams of sugar, and probably approaches 200 calories. I think that the average American consumes a lot more sugar than just 50 g a day.

Just some friendly feedback.

### Re: Fermi Questions C

Ok, thanks. I just figured that not all the calories in a can of soda come directly from sugar, and also that people eat a healthy amount. I probably am a bit low though.

If an army of 500 industrious beavers wanted to log the entire Amazon rainforest, how long would it take them in days?

If I funneled the world's oceans into a cylindrical column of radius 1 meter, what would be the pressure at the bottom, in atmospheres?

Mind you, the average oceanic depth is a lot deeper than 10 m. Continental shelves alone are usually hundreds of meters deep, and the abyssal plains are usually many thousands of meters deep. For example: the Barents Sea, one of the shallower large expanses of water on the planet, is only about 100 meters deep, though it may reach 200 near the deeper parts. In contrast, Challenger Deep, off the Marianas Island Arc, is about 11 kilometers deep.

Yeah, that's a good point. I think that bumps my answer up by 2 then.

How fast would Santa have to travel to visit every child in the world in one 24-hour period?
