1.1. The Eiffel Tower has a height of 324 m and weighs 10000 tons. How many kilograms will a copy with a height of 1.62 m weigh?
Answer: 1.25. Solution. The volumes of similar bodies are in the ratio of the cube of the similarity coefficient. Since the similarity coefficient is $\frac{324}{1.62}=200$, the weight of this copy of the Eiffel Tower is $\frac{10000}{200^{3}}$ tons, which equals $\frac{10^{7}}{8 \cdot 10^{6}}=\frac{10}{8}=\frac{5}{4}=1.25$ kg.
