![\bf \cfrac{\textit{similar shape}}{\textit{similar shape}}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\\\\ -------------------------------\\\\ \cfrac{small}{large}\qquad \qquad \cfrac{s}{s}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\implies \cfrac{3}{h}=\cfrac{\sqrt[3]{27}}{\sqrt[3]{125}}\implies \cfrac{3}{h}=\cfrac{3}{5}\implies \cfrac{3\cdot 5}{3}=h](/tpl/images/0109/8125/b5c2f.png)
