How did the Colisseum compare in size to other Roman structures? Watch the following video then answer the questions: History Of RomanColisseum...

The answer to this can be found at about 2 minutes in to
the video that you have linked to.  Basically, the Colosseum was bigger (or at least
taller) than any other building built in Ancient Rome.  We are not told how much taller
it was than any other building.  We are also not told how its overall size (other than
its height) compared to the other large buildings of
Rome.

According to the video, the Colosseum eventually
reached a height of about 160 feet.  This was possible because of the Romans' ability to
use things like cranes to lift heavy stones.
