Question

calculati lungimea diagonalei paralepipedului dreptunghis : L=3cm,l=2cm si h=6cm​

Answer 1

 

$\displaystyle\bf\\Diagonala~paralelipipedului~se~calculeaza~cu~formula:\\\\d_{paralelipiped}=\sqrt{L^2+l^2+h^2}\\\\Rezolvare:\\\\d_{paralelipiped}=\sqrt{L^2+l^2+h^2}\\\\d_{paralelipiped}=\sqrt{3^2+2^2+6^2}\\\\d_{paralelipiped}=\sqrt{9+4+36}\\\\d_{paralelipiped}=\sqrt{49}\\\\\boxed{\bf d_{paralelipiped}=7~cm}$
