since there are 264 gallons(US) in 1 m³, how many gallons(US) are there in 234 m³?
[tex]\bf \begin{array}{ccll} US~gallon&meter^3\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
264&1\\
g&234
\end{array}\implies \cfrac{264}{g}=\cfrac{1}{234}\implies \cfrac{264\cdot 234}{1}=g[/tex]
