$w = 3\sqrt{3}$ $x = \frac{9\sqrt{3}}{2}$ $y = \frac{9}{2}$ $z = \frac{3\sqrt{3}}{2}$

$\frac{w}{9} = \frac{1}{\sqrt{3}}$ $w = \frac{9}{\sqrt{3}}$ $w = 3\sqrt{3}$ $\frac{x}{9} = \frac{\sqrt{3}}{2}$ $x = \frac{9\sqrt{3}}{2}$ $\frac{y}{9} = \frac{1}{2}$ $y = \frac{9}{2}$ $\frac{z}{w} = \frac{1}{2}$ $z = \frac{w}{2}$ $z = \frac{3\sqrt{3}}{2}$
