Szczegółowe wyjaśnienie:
przekątna d = a[tex]\sqrt{2}[/tex]
[tex]a\sqrt{2}[/tex] = 14cm
a = [tex]\frac{14}{\sqrt{2} }[/tex]
a = [tex]\frac{14\sqrt{2} }{2}[/tex] = [tex]7\sqrt{2}[/tex] cm
Pc = 6* [tex]a^{2}[/tex] = 6* [tex](7\sqrt{2})^{2}[/tex] = 6* 98 = 588 [tex]cm^{2}[/tex]
V = [tex]a^{3}[/tex]
V = [tex](7\sqrt{2})^{3}[/tex] = [tex]686\sqrt{2}[/tex] [tex]cm^{3}[/tex]
