30 mm is equivalent to 1.1811 inches.
The same object that is 11.5 cm long
Africa oldest crocodile

3.4 cm equals 34 mm which is greater than 30 mm
The same object that is 11.5 cm long
1 mm = 1000 um 0.03 mm = 30 um
Not very long. Are asking about a conversion or an object that's 80mm long?

To get the kinetic energy of an object you need both mass and velocity. As it stands it can't be answered, as "mm" isn't a recognized unit of velocity
A lock on a door knob.

There is no object with a volume of 2000 mm because the "mm" is a unit of length NOT volume.
30 mm = 0.098425 '
1 cm = 10 mmThen 30 mm is larger than 1 cm.
The distance between the object and mirror is 15 mm. The distance between the image and mirror is 15 mm. Therefore, the distance between the image and object is 15 mm plus 15 mm which equals 30 mm.
There are 1,000 millimetres in a metre. Therefore: 6 metres 30 centimetres.
