urgent!!dau coroana!!

Answer 1

[tex] P_{b} =4*l \\ P_{b} =4*2=8m \\ A_{cort} = A_{t .piramida} \\ A_{l} = P_{b} * \frac{apotema}{2} \\ A_{l} = 8 * \frac{2}{2} \\ A_{l}=8 \\ A_{b} = l^{2} = 2^{2} =4 A_{t} = A_{l} + A_{b} =8+4=12 \\ V_{tr.piramida} = \frac{h}{2} *( A_{B} + A_{b}+ \sqrt{ A_{B}* A_{b}}) \\ h_{piramida} .si. apotema_{piramidei}. si. apotema_{bazei} \\ alcatuiesc. un. triunghi. dreptunghic. din. care. aflam. inaltimea. \\ VO= \sqrt{ VM^{2} * OM^{2} } \\ VO = \sqrt{4*1} \\ VO=2 \\[/tex]
