If you need to measure the volume of liquid in a bottle of eyedrops, what unit would be the most practical?

-kiloliter
-milliliter
-dekaliter
-liter

The correct answer is B. Milliliter

Explanation:

Volume, which refers to the space a liquid, solid, etc. occupies can be measured using different units such as milliliter that is one of the smallest units, liter that is the most common one and is equivalent to 1000 milliliters; dekaliter than is equivalent to 10 liter and kiloliter that is the equivalent to 1000 liters. This means, if you need to measure the volume of a liquid in a bottle of eye drops that is usually a small container, the best is to use the milliliter as a unit because this is the smallest unit from the options given and therefore the more suitable for measuring small volumes precisely. Indeed, most bottles of eye drops contain around 5 or 10 milliliters.
