[tex]V = \frac{1}{3} Pp * H\\\\1.\\Pp = 4 * 4 = 16cm^{2} \\V = \frac{1}{3} * 16cm^{2} * 10cm = \frac{160}{3} cm^{3} = 53 \frac{1}{3}cm^{3} \\2. Pp= \frac{a^{2}\sqrt{3} }{4} = \frac{2^{2} \sqrt{3} }{4} = \frac{4\sqrt{3} }{4} = \sqrt{3}cm^{2} \\V = \frac{1}{3} * \sqrt{3} cm^{2} * 8cm = \frac{8\sqrt{3} }{3} cm^{3} \\3. Pp = \frac{a^{2}\sqrt{3} }{4} * 6 = \frac{2^{2}\sqrt{3} }{4} *6 = 6\sqrt{3} cm^{2} \\V = \frac{1}{3} *6\sqrt{3}cm^{2} * 20cm = 2\sqrt{3} cm^{2} * 20cm = 40\sqrt{3} cm^{3}[/tex]
Mam nadzieję że pomogłam i liczę na naj. ♥
