3.4 cm
If you mean 3.4 mms or 30 mms then 30 is larger.
In terms of length, 30mm is greater than 3cm. This is because 1cm is equal to 10mm. Therefore, 3cm is equivalent to 30mm.
I believe you are trying to ask which MEASUREMENT is bigger. There are 10 mm in a cm, so you can multiply 3.4 cm by 10 to get 34 mm; which is bigger.
30mm*230mm = 6900 millimetres = 271.653543 inches
