Question

Large office buildings are often as big as small towns．They have their own trains，buses，and shops．Such buildings can be found in most cities around the world．When it was built，however，in 1943，the Pentagon（五角大楼）was the world's largest office building．It is，still many years later，among the largest．

The Pentagon is different from all other office buildings，however，because it is used by only one organization．This is the United States Defense Department，the headquarters（HQ）of the United States military--the army，the navy，and the airforce．When people think of the military strength of the USA，they usually think of the Pentagon．

The Pentagon was built across the Potomac River from Washington，DC，during the second World War．It took only two years to build in spite of its huge size．

Built in the shape of a pentagon--a five-sided figure--the building consists of five circles，divided into ten sections．Each side of outside pentagon is about 300 meters long．In the centre，there is a large space open to the sky．

Six stories high，the Pentagon has a total floor space of about two million square meters．Around it，there are about 45 kilometers of roads that are part of the building，and inside the building itself there are over 25 kilometers of passages．In spite of its great size，however，no office is more than a six-minute walk from any other office in the building．

Thirteen thousand people worked on building the Pentagon，and about thirteen thousand now work in it for the Defense Department．It cost 80 million dollars to build in 1943-a huge sum at that time，and one that many Americans thought it was too much．However，if the Defense Department had to rent such a building now，it would cost it around $30 million a day! The building was，therefore，a bargain．
