Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle V = \frac{lwh}{3}$

Step 2: Solve for h

[Multiplication Property of Equality] Multiply 3 on both sides: $\displaystyle V = \frac{lwh}{3} \rightarro 3V = lwh$
[Division Property of Equality] Divide lw on both sides: $\displaystyle V = \frac{lwh}{3} \rightarrow h = \frac{3V}{lw}$
