Wat about which of the following is the largest volume 1.2x10^1 m3 1.2x10^8 cm3 2.0x10^4 dm3 1.2x10^8 mm3

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.
