Answer 2

0.012 Dekameters (mm) is not equal to 120 centimeters.

Step-by-step explanation:

1 km = 1000 m

1 m = 100 cm

Then 1000 m will be equal to :

1000 m = 1000 × 100 cm = 100,000 cm

So, 1 km = 100,000 cm

Then 120 cm will be equal to: 0.0012 km

1 m = 100 cm

Then 120 cm will be equal to: 1.2 m

1 Dm = 1000 cm

Then 120 cm will be equal to: 0.12 Dm

1 cm = 10 mm

Then 120 cm will be equal to: 1,200 mm
