About the height of a giraffe

It is said that many males exceed 5.5 m in height.
A record height for a giraffe in a UK zoo was 5.8 m, but the tip of his horns was said to have reached close to 6.1 m.
So 6 m is about in this ballpark.

Or in natural units: three very tall men stood on top of one another, wearing a top hat.

Are all three men wearing individual top hats, or does one cover all of them?

Oh jeez, how many football fields is that?

Let’s see. 2 cm of grass on top of, say, 10 cm of earth would make the height of a football field 12cm. That would make it as high as about 50 football fields.

It's not a rocket, but three men in a trench coat?
