Question

what is the metric system unit for volume?
○ $m^3$
○ $m^2$
○ $ft^2$
○ $ft^3$

Explanation:

Volume is a 3-dimensional measurement, so its unit has a cubic exponent. The metric system uses meters (m) as a base unit for length; thus, cubic meters ($m^3$) are the metric unit for volume. Options with $m^2$ (area) or feet (imperial unit) are incorrect.

Answer:

A. $m^3$
