Standing on ground How can you tell 400 feet in the air ?

Question

Can you use building or floor flight for an example

Answer

On average in general one story equals 10 feet.  A 40 story building is approximately 400 feet.

"The height of each storey is based on the ceiling height of the rooms plus the thickness of the floors between each pane. Generally this is around 10 feet (3 m) total; however, it varies widely from just under this figure to well over it."
