Odpowiedź:
a)
[tex]V = abc\\V= 4 * 4 * 8 = 128j^{2}[/tex]
b)
Na to jest wzór:
[tex]V = \frac{a^{2}\sqrt{3} }{4} * H\\\\V = \frac{9\sqrt{3}}{4} * 7\\\\V = \frac{63\sqrt{3} }{4} j^{2}[/tex]
c)
Wzór na to:
[tex]V = \frac{3a^{2} \sqrt[]{3} }{2} *H[/tex]
[tex]V = \frac{12\sqrt[]{3}}{2} * 9\\\\V = 54\sqrt{3} j^{2}[/tex]
