Convert the given volumes to quantities with the same units. For this item, convert all volumes to m³
 
 (1) 1.2x10 m³  =  12 m³
 (2) 1.2x10^8 cm³   x (1 m / 100 cm)³ = 120 m³
 (3) 2.0x10^4 dm³ x (1 m / 10 dm)³ = 20 m³
 (4) 1.2x10^8 mm³ x (1 m / 1000 mm)³ = 0.12 m³

The least among the given is the fourth choice, 1.2x10^8 dm³.
