Question

120km3+10dam3=......m3

Answer 1

120 km3 = 120.000.000.000 m3
10 dam3 = 10.000 m3
hasilnya 120.000.001.000

Answer 2

1 km³= 10^9 m³
120 km = 120×10^9 m³
= 1,2×10^11 m³
1 dam³= 10^3 m³
10 dam³ = 10× 10^3 m³
= 10^4 m³
120 km³+ 10 dam³= (1,2×10^11)+10^4 m³
= 1,2000001×10^11 m³
= 120.000.010.000 m³
