Answer:
Meters
Step-by-step explanation:
As we can see that iceberg Is not so small so using the inches and millimeters for measuring its height would be a very Unit and we will need a lot of inches to do so
In case of square centimeters and square kilometers we can not use these kind of units to measure the height of an iceberg because of the reason that these are the units of the area and height is in this case is the distance between bottom to top so for measuring distance we can not use the units of area
In case of kilo meter it is a large unit to measure the height of the ice berg. It could be used to measure height but in this case we will get the answer in very small values so scaling it would not be easy
So the last option left with us is meters which would be used to measure the Height of the ice berg it is also the SI unit of length so it is also the best unit because it is either not so small or not so large so that why it could be used.
Also meters is used by the scientists too so it is a standard unit and all other units are created from it. This gives all scientists the same standards of measurement during an experiment.
