A cooler measures 30 cm wide, 30 cm long, and 25 cm tall. Which is the correct unit of measurement to use when describing the amount of ice that will fill the cooler? A. cm2 B. cm3 C. cm

The correct answer is B. cm3

This is saying "centimeters cubed", and is true because you are multiplying 3 dimensions of centimeters, width*length*height, to get the answer. Thus, you are multiplying the numbers and the units. 30*30*25 and cm*cm*cm
