Eiffel Tower

Eiffel Tower in Paris is 300 meters high and is made of steel. Its weight is 8000 tons. How tall is the tower model made ​​of the same material if it weighs is 2.4 kg?

Correct answer:

Model height:  2 m

Step-by-step explanation:

h1=300 m m1=80001000=8000000 kg m2=2.4 kg  V=abh=k1hk2hh=k1k2h3=Kh3  ρ=m1V1=m2V2 m1V1=m2V2 m1Kh13=m2Kh23 m1h13=m2h23 m1m2=h13h23 m1m2=(h1h2)3  m1m23=h1h2  h2=h1/m1m23  h2=300800010002.432 m
