The metal structure of the Eiffel Tower has a mass of 7300 tons, or 7.3 million kilograms. The design of the tower is very space-efficient: if you melted down the pure iron* that it is made of, it would occupy a volume of only 930m3, equivalent to a sphere with a radius of just six metres.
Its base is square, 125 metres (410 ft) on a side. During its construction, the Eiffel Tower surpassed the Washington Monument to assume the title of the tallest man-made structure in the world, a title it held for 41 years, until the Chrysler Building in New York City was built in 1930.he Eiffel Tower (/ËaÉªfÉl ËtaÊÉr/ EYE-fÉl TOWR; French: tour Eiffel [tuÊâ¿ÉfÉl] listen) is an iron lattice tower located on the Champ de Mars in Paris, France.
