Given:
[tex]V=\text{LWH}[/tex]To make H the subject of the formula
Step 1: Find the coefficient of H
The coefficient of H is LW
Step 2: Divide both sides by the coefficient of H
[tex]\frac{V}{LW}=\frac{LWH}{LW}[/tex][tex]\frac{V}{LW}=H[/tex]Making H the subject of the formula
[tex]H=\frac{V}{LW}[/tex]Option A is correct
