![\bf \cfrac{small}{large}\qquad \cfrac{s}{s}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\implies \cfrac{1}{3}=\cfrac{\sqrt[3]{35.28}}{\sqrt[3]{v}}\implies \cfrac{1}{3}=\sqrt[3]{\cfrac{35.28}{v}} \\\\\\ \left( \cfrac{1}{3} \right)^3=\cfrac{35.28}{v}\implies \cfrac{1^3}{3^3}=\cfrac{35.28}{v}\implies v=\cfrac{3^3\cdot 35.28}{1^3}](/tpl/images/0397/7067/cc815.png)
