Final answer:
The SI units for mass, length, and volume are kilograms (kg), meters (m), and cubic meters (m³) respectively. Grams (g) and liters (L) are also commonly used for mass and volume, particularly in laboratory settings.
Step-by-step explanation:
The International System of Units, commonly known as the SI units, is the modern form of the metric system and is the most widely used system of measurement for science and international commerce. In the SI system, the base units for mass, length, and volume are:
- Mass: The kilogram (kg) is the base unit of mass. In practice, the gram (g) is also commonly used, which is 1/1000 of a kilogram.
- Length: The meter (m) is the base unit of length. For smaller or greater distances, metric prefixes are used, such as millimeters (mm) for small lengths and kilometers (km) for larger distances.
- Volume: The cubic meter (m³) is the derived unit of volume in the SI system, defined as the volume of a cube with sides of one meter. However, for fluids and gasses, the liter (L), which is equivalent to 1000 cubic centimeters (cc), is commonly used.
Answering the student's question, the measuring units of mass, length, and volume are respectively: kilograms, meters, and cubic meters, which corresponds to option (a).
