Масса металла, из которого построена Эйфелева башня, равна7300 тонн.

Плотность металла (железа) равна 7,8 кг/дм3.

Чему равен весь объем металла, из которого построена башня?

Дайте ответ в кубических метрах.


Представим себе, что весь этот металл расплавили и залили им квадратную площадку со стороной 125 метров (расстояние между опорами башни равно 125 метров). Тогда получится металлическая плита с квадратным основанием.

Чему будет равна толщина такой плиты? Дайте ответ в сантиметрах.
