Final answer:
A unit of volume measure can be cubic meters (m³), liters (L), or milliliters (mL), with the liter being commonly used in scientific settings for its manageability.
Step-by-step explanation:
The unit of volume is a measure of the amount of space occupied by a sample of matter. Common units of volume include the cubic meter (m³), the liter (L), and the milliliter (mL). The cubic meter is the SI unit for volume and is defined as the space occupied by a cube with 1 meter on each side. In practical terms, a liter, which is equal to one cubic decimeter (1 dm³) or 1000 cubic centimeters (1000 cm³), is often used, as it is manageable and commonly applied in various scientific settings. The milliliter is a smaller unit of volume, equivalent to the volume of a cube that measures 1 cm on each side, or one cubic centimeter (1 cm³).
