Answer:
120 cubic meters
Step-by-step explanation:
Three-dimensional measurement is basically any unit of measurement cubed. Since grams is just to the first power, it is not considered three-dimensional. miles per hour is a fraction, so it is not a three-dimensional measurement of volume. 120 units are to the first power, so you are left with 120 cubic meters, which is a three-dimensional measurement of volume. Also, another way to solve this is to look at the types of measurement. The cubic meter is a measure of volume. Grams are a measurement of mass. Miles per hour is a measurement of speed. Units can be any type of measurement because you can substitute units instead of any measurement in questions.
