Tower Square

Can you prove the following as fact? Weight of Eiffel Tower = Weight of Air defined by Eiffel Tower.?
What I mean by the weight of air defined by the Eiffel Tower is the air in the parallelipiped defined by the four feet of the Eiffel Tower (square) and the height of the Eiffel Tower.
I can disprove the theory.
The Eiffel tower weighs 10,000 tonnes (approx).
The tower is 324m high (since latest antenna added) and has a base 125m square.
The air cylinder which would surround the tower (176m dia and 324m high) would weigh 2,394 tonnes at 20 degrees C. The weight of air displaced by the tower envelope would be considerable less than this.
