[tex]pc = 2 \times \frac{3 {a \sqrt{3} }^{2} }{2} + 6ah = 3 \times {6}^{2} \sqrt{3} + 6 \times 6 \times 12 = 108 \sqrt{3} + 432 = 108( \sqrt{3 } + 4)\: {cm}^{2} [/tex]
[tex]v = pp \times h = \frac{3 {a}^{2} \sqrt{3} }{2} \times h = \frac{3 \times {6}^{2} \sqrt{3} }{2} \times 12 = 648 \sqrt{3} \: {cm}^{3} [/tex]
[tex] \sum \: krawedzi = 12 \times 6 + 6 \times 12 = 72 + 72 = 144 \: cm[/tex]
