Odpowiedź:
zad 1
wzór
V=1/3a2*H
[tex]v = \frac{1}{3} \times {11}^{2} \times 18 = \frac{1}{3} \times 121 \times 18 = 726 {cm}^{3} [/tex]
zad.2
wzór
V=1/3*Pp*H=1/3*(a3✓3)/4*H=(a3*H✓3)/12
[tex]v = \frac{ {a}^{3} \times h \sqrt{3} }{12} [/tex]
[tex]v = \frac{ 12 \times {6}^{3} \sqrt{3} }{12} = {6}^{3} \sqrt{3} = 216 \sqrt{3} [/tex]
