The word "cubic measures" refers to the measurement of volume or capacity of a three-dimensional space or object. The antonyms of cubic measures would be the measurements of length or distance, such as meters, inches, feet or yards. These units of measurement are used to determine the size or dimensions of one-dimensional or two-dimensional objects. Moreover, other antonyms for cubic measures could be weight or mass, which are used to determine the amount of matter in an object. Therefore, while cubic measures focus on volume, antonyms of cubic measures focus on different aspects of objects and spaces, such as length, weight, and mass.
