The Twin Towers, part of the World Trade Center, were primarily constructed with steel rather than ferrihydrite, which is a type of iron oxide mineral. The steel framework provided structural support for the towers, which were about 110 stories tall. When the planes crashed into the towers on September 11, 2001, the impact and ensuing fires caused significant structural damage, ultimately leading to the collapse of both buildings. The exact amount of ferrihydrite is not relevant in this context, as the towers' collapse was due to the failure of the steel structure under extreme heat and stress.
