Any of those may be used, but "meter" will result in the most convenient number.
A tree is measured in meters, except for very young tree measured in centimeters.
A cubic centimeter is a unit of volume and kilometer is a unit of distance. You cannot place cubic centimeters "into" a kilometer. If anything you can place cubic centimeters into a cubic kilometer. The answer to that would be: 1 cubic kilometer = 1e+15 cubic centimeter Which is basically a huge number: 1,000,000,000,000,000 cubic centimeters fit into one cubic kilometer. On the other hand you can line up 100,000, 1 centimeter (1cmx1cmx1cm) cubes in a straight line and their combined length would equal to one kilometer.
it depends on about how big it is but i would guess meters or centimeters

How much a bicycle what? Weighs, cost, take up space?
Vehicles are not measured in terms of Kilometers. A meter scale would be more appropriate to describe the length of a vehicle, even a bus.
No. It would be measured in pages
You would use the unit of meters to measure the length of 10 football fields.
from largest to smallest it would be: km, m, cm, mm
Centimeter (cm), inch (in), foot (ft), yard (yd), meter (m), kilometer (km), mile (mi).
You would measure it in centimeters.
If the scale is 1 centimeter to 1 kilometer, then the actual distance represented by the scale distance would be 1 kilometer for every 1 centimeter on the map. This means that if you measure a distance of, say, 5 centimeters on the map using this scale, the actual distance in real life would be 5 kilometers.
