Question

what is the base unit of volume when using the metric system?
a liter or l
b milliliter or ml
c cubic centimeter or cm³
d cubic meter or m³

Explanation:

Step1: Understand metric system base units

In the metric system, base units are fundamental.

Step2: Recall volume base unit

The base unit of volume in the metric system is the cubic meter (\(m^{3}\)). A liter (\(L\)) is a derived unit (\(1L = 1dm^{3}\)), a milliliter (\(mL\)) is \(1cm^{3}\) (also a derived unit), and while \(cm^{3}\) is used, it's not the base unit. The base unit for length is meter (\(m\)), so for volume (length\(\times\)length\(\times\)length) the base unit is \(m^{3}\).

Answer:

D. cubic meter or \(m^{3}\)
