Question

Aria totala laterala si volumul unui cub stiind ca suma muchiilor e de e de 36

Answer 1

Un cub are 12 muchii egale, deci daca suma lor este 36,fiecare are
l=3
Atot =6*Afata=6*l^2=6*9=54
Alat=4*Afata=4*l^2=36
Vcub=l^3=27

Answer 2

$\text{Cubul are 12 muchii} \rightarrow 36:12 = 3 \text{ cm latura cubului.} \\ \\ V_{cub}=A_b \cdot h = l^3 = 3^3 = \boxed{27~cm^3} \\ \\ A_l = P_b \cdot h =4 \cdot 3 \cdot 3 = \boxed{36~cm^2}$
