Question

Un cub are volumul de 1000cm. Aflati aria suprafetei totale a cubului

Answer 1

V=1000cm
v=l³
V=10³
=> l=10 cm
Atotala=6l²
A=6 x 10 x 10
A= 600 cm²

Answer 2

V= $l^{3}$
1000$cm^{3}$ = $l^{3}$=>$10^{3}$ = $l^{3}$
atunci l = 10 cm
$A_{t}$ = $6* 10^{2}$ => $A_{t}$ = 6 l^{2} [/tex] =>$A_{t}$=6*100 =>A_$A_{t} =600 cm^{2}$
