* Blue Whale Size: The average blue whale is about 100 feet long and weighs around 200 tons. That's HUGE!
* Human Size: The average human is about 5' 4" tall and weighs around 137 pounds.
* Space and Shape: The problem is that humans are not perfectly packed like sardines. There would be lots of wasted space due to our limbs, uneven shapes, and the need for breathing room.
Rough Estimation:
* Volume: We can estimate a rough volume for a blue whale and a human. A rough approximation is to think of them as elongated cylinders.
* Packing: We could try to estimate the space needed to fit humans tightly together, but it would be a very rough guess.
Conclusion:
It's safe to say that you could fit hundreds of humans inside a blue whale, but not thousands. It would be a very uncomfortable and impractical situation!
