# Can you help me with this equation? Solve for h SA=2lw+2lh+2hw

$SA = 2lw + 2lh + 2wh$ $SA = 2(lw) + 2(lh) + 2(wh)$ $SA = 2(lw + lh + wh)$ $\frac{SA}{2} = \frac{2(lw + lh + wh)}{2}$ $\frac{1}{2}SA = lw + lh + wh$ $\frac{1}{2}SA - lw = lw - lw + lh + wh$ $\frac{1}{2}SA - lw = lh + wh$ $\frac{1}{2}SA - lw = h(l) + h(w)$ $\frac{1}{2}SA - lw = h(l + w)$ $\frac{\frac{1}{2}SA - lw}{l + w} = \frac{h(l + w)}{l + w}$ $\frac{\frac{1}{2}{SA}}{l + w} - \frac{lw}{l + w} = h$
