Dobrý deň, potrebovala by som pomoc s touto úlohou:
Pravidelný 4-boký ihlan má veľkosť bočnej hrany s = 2 a , strana jeho štvorcovej podstavy má veľkosť a=5 . Vypočítajte objem a povrch ihlana.
Viem, že neznáme hodnoty potrebné do vzorcov na výpočet sa dajú vypočítať cez Pytagorovu vetu, avšak nejak mi nikdy nesedia dĺžky strán pravouhlých trojuholníkov. Vopred ďakujem za pomoc!
