Final answer:
The SI base unit for length is meter (m), for mass is kilogram (kg), for volume is cubic meter (m³) or liter (L), and for area is square meters (m²) or square centimeters (cm²).
Step-by-step explanation:
In the SI (International System of Units), various measurements are used for different physical properties. The meter (m) is the SI base unit for measuring length or distance. When talking about the mass of an object, the SI unit is the kilogram (kg). To measure volume, which is the amount of space occupied by an object, a derived unit based on the meter is used, such as the cubic meter (m³) or for smaller volumes, the liter (L) which is equivalent to one cubic decimeter (dm³) or 1000 cubic centimeters (cm³). Area is measured in square meters (m²) or for smaller areas, in square centimeters (cm²).
