Question

o prisma patrulatera regulata are muchia bazei doi,si muchia laterala2√2 Aflati Al?,At? V?

Answer 1

latura bazei = 2 si muchia laterala = 2rad.2 ...
= > A (laterala) = P (bazei) * h = (4*2)*2rad.2=16rad.2 ;
      A (totala)    = 16rad.2+2*(2^2)=16rad.2+8=8(2rad.2+1) ;
      V= A(bazei)*h = 2^2 * 2rad.2=8rad.2 ;
