Chapter 2.2, Problem 5QQ
Interpretation Introduction
Interpretation:
One cubic centimeter equivalent has to be chosen from the given options.
Concept Introduction:
Meter is the base unit of length and liter is the base unit of volume. These units are interrelated to each other. For example, the volume occupied by one liter is same as that of a cube whose length is 10cm on each of its sides.
