Good. I will post more if I think of any.

Oh, here is one:

Q:"If a room 4x4x2 was filled with as much McDonald's hamburgers and a starving person somehow absorbed every single calorie out of it, would it be enough to have him run once around the Earth? If not, then what would be the smallest room filled with hamburgers that would enable him to do that?"

Here lies the reader who will never open this book. He is forever dead.

It would depend on what you mean by running around the earth. A great circle?

4x4x2? Meters, inches, feet?

Wait, I asked that same question for the popcorn question. You answered in meters. Hold on calculation is coming...

A typical burger (quarter pounder ) of this type has a 4'' diameter bun. This can verified on the net and was standard from 2009. We round this to .1 m

We estimate its height at about .05m high and it is approximately cylindrical in shape. This burger then has a volume of .00078539 cubic meters.

The room has a volume of 32 m^3, so 40000 burgers (quarter pounders ) can be stuffed into the room. The caloric intake of one burger is 460 calories.

Now everyone on this planet and many others knows that you can walk briskly(4 mph ) for 20 minutes on 4 calories! So you can probably run for 5 minutes ( assuming a near linear relationship ) on 4 calories. Let's round this to 5 calories or 1 calorie provides 1 minute of running at say 12 mph.

We have a total calorie count of:

That is

of running at 12 mph.

So we can run around the earth approximately

147 times.
