Question

Am nevoie de help now pliz.Coroana garantata

Answer 1

14 ) V=3dm*3dm*3dm=27dm^3
9l=9dm^3 ...

Vdreptunghi=3dm*3dm*h dm=9dm^3
=> h=1 dm =10cm
15) 1) V=10*6*4=240 m^3
2) V=8*5*6=40*6=240 m^3.
Sunt egale ca volum
1) At= 2* (10*6 +10*4 + 6*4 )=2*(60+40+24)=2*124=248 m^2
2) At=2(5*6+6*8+8*5)=2(30+48+40)=2*118=236m ^2.
Prima are aria totală mai mare.
