cześć!
[tex]v = \frac{1}{3} pp \times h[/tex]
pole podstawy:
[tex]pp = \frac{ {a}^{2} \sqrt{3} }{4} \\ pp = \frac{ {5}^{2} \sqrt{3} }{4} \\ pp = \frac{25 \sqrt{3} }{4} [/tex]
h=6cm
[tex]v = \frac{25 \sqrt{3} }{4} \times 6 \\ v = \frac{150 \sqrt{3} }{4} \\ v = \frac{75 \sqrt{3} }{2} [/tex]
pozdrawiam!
