It is longer: One mm goes into a cm 10 times. 50 mm is more than 4 mm.
not igzackly there the same measure

I am not sure what the point is for you to give us the dimensions of a rectangle and then ask what one of those dimensions is. Perhaps you are not sure whether the shorter or the longer of the two dimensions would be considered the length, and which the width. I would say that a rectangle measuring 2cm x 5cm is 2cm wide and 5cm long.
He's 173cm (5'8"). He's 5cm (2 inches) shorter than Hiroyuki Takami. Both men are in the band "Access".
witch is longer 5cm or 5 inches
true
13 cm
1mm=0.1cm, therefore 30mm=3cm. 3cm is less than 5cm so 5cm is indeed greater than 30mm.
No, they are both the same.
This is impossible to answer as it depends on the density of the material. I.e. a 125 cm3 of lead is significantly heavier than a 125 cm3 cube of foam rubber.
5cm*5cm*5cm = 125 cubic cm.
