How many floors does a 400 foot tall building have?

The number of floors in a 400-foot tall building can vary significantly based on the height of each floor. Typically, commercial buildings have floors that are around 10 to 12 feet high, while residential buildings may have shorter floors, around 8 to 10 feet. Assuming an average height of 10 feet per floor, a 400-foot building would have approximately 40 floors. However, this number can change based on architectural design and the purpose of the building.
