How many liters are there in a cubic meter?

A cubic meter is a unit of volume defined as the volume of a cube with each edge measuring one meter in length. Since one liter is equivalent to one cubic decimeter (0.1 meter on each side), it follows that there are 1,000 cubic decimeters in one cubic meter. Therefore, when converting from cubic meters to liters, the relationship indicates that each cubic meter contains 1,000 liters. This fundamental understanding of metric volume conversion supports the selection of the answer indicating that there are 1,000 liters in a cubic meter.

The other choices do not represent the correct conversion factor from cubic meters to liters, as they either underestimate or overestimate the actual number of liters contained in a cubic meter.
