Answer 1

Lungime: 4.000km=4.000.000m;
4.000dm=400m;
4.000mm=4m.
Arie: 20km^2=20.000.000m^2;
20ha=20hm^2=200.000m^2;
20ar=20dam^1=2.000m^2;
20dm^2=0,2m^2;
20mm^2=0,00002m^2;
Volum: 5km^3=(5^3)*(10^9)m^3=(5^3)*(10^12)dm^3=(5^3)*(10^12)litri;
500dm^3=500l;
5.000.000cm^3=5l;
Capacitatea: 8.000ml=8l;
800ml=0,8l;
80ml=0,08l;
8ml=0,008l.
Masa: 70t=70.000kg;
70q=7.000kg;
70g=0,07kg;
70mg=0,007kg.
Timp: 300min=18.000s;
3ore=10.800s.
Sper ca ti-am fost de ajutor :)
