Solve the equation for the stated variable: V=lwh. Solve for h

H = v/lw

Basically, in order to solve for h, you have to get h by itself. The way you would do that is divide lwh by lw in order to leave h by itself.

v = lwh/lw

But what you do to one side of the equation, you have to do to another, so you would also divide v by lw.

v/lw = lwh/lw

v/lw = h
