Answer
w = (3V/lh)
Explanation
We are asked to solve for w in
V = ⅓ (lwh)
V = (lwh/3)
[tex]\begin{gathered} V=\frac{\text{lwh}}{3} \\ \text{Cross multiply} \\ \text{lwh = 3V} \\ We\text{ then divide both sides by lh} \\ \frac{\text{lwh}}{lh}=\frac{3V}{lh} \\ w=\frac{3V}{lh} \end{gathered}[/tex]Hope this Helps!!!
