Answer 2

Hello!!

 There are various types of measurement,

1 cm = 10mm (millimeter)

=>  30 cm = 300 mm,

1cm = 0.45 inch,(approx)

=> 30 cm = 12 inch

1cm = 0.1dm (decimeter),

=> 30cm = 3dm

1 cm = 0.01 (meter)

=> 30cm = 0.3m(meter)

1 cm = 1x $10^{-3}$  dam (decameter)

=> 30 cm = 0.03 dam

1 cm = $10^{-4}$ hm (hectameter)

=> 30 cm = 3 x $10^{-3}$ hm

1 cm = $10^{-5}$ km (Kilometer)

=> 30 cm = 3 x $10^{-4}$ km
