Răspuns :
a) Avem L=10,h=12 si l=5
Aria totala este data de formula:
[tex]2(L*h+l*h+l*L) = 2( 10*12+5*12+5*10)= \\ 2(120+60+50)=2*230=460 [/tex]
b)Volumul:
[tex]L*l*h=5*10*12=50*12=600[/tex]
Aria totala este data de formula:
[tex]2(L*h+l*h+l*L) = 2( 10*12+5*12+5*10)= \\ 2(120+60+50)=2*230=460 [/tex]
b)Volumul:
[tex]L*l*h=5*10*12=50*12=600[/tex]
-> A totala paralelipiped = 2*(L*h+l*h+l*L) = = 2(120+60+50)=460
-> Volum paralelipiped=L*l*h=5*10*12=600
-> Volum paralelipiped=L*l*h=5*10*12=600
