Question

O prisma patrulatera regulata are l=4 cm si h=5 cm . Aflati aria toatala si volumul

Answer 1

Perimetrul Bazei(Pb) = 4l
Pb = 4 x 4 => Pb = 16 cm

Aria Laterala(Al) = Pb x h
Al = 16 x 5 => Al = 80 cm^2

Aria Bazei(Ab) = l^2
Ab = 4^2 = 16 cm^2

Aria Totala(At) = Al + 2Ab
At = 80 + 2x16
At = 112 cm^2

Volumul(V)  = Ab x h
V = 16 x 5
V = 80 Cm^3
