Given the formula:
[tex] \displaystyle \large{V= \frac{1}{3} Ah}[/tex]
We want to isolate A-term. First, 1/3 • Ah can be written as:
[tex] \displaystyle \large{V= \frac{Ah}{3}}[/tex]
Since we have 3 as the denominator, we multiply the whole equation by 3.
[tex] \displaystyle \large{V \times 3= \frac{Ah}{3} \times 3} \\ \displaystyle \large{3V= Ah}[/tex]
Then we move h to divide 3V since h is multiplied by A.
[tex] \displaystyle \large{ \frac{3V}{h} = A}[/tex]
Therefore, A = 3V/h
