Which of the following units is commonly used to measure volume in the SI system?

• A. second (s)
• B. liter (L)
• C. gram (g)
• D. meter (m)

Answer: (B)

Verified step by step guidance

1. Understand that the SI system (International System of Units) has base units for different physical quantities. For volume, the SI system uses derived units based on the meter.
2. Recall that volume is a measure of the amount of space an object occupies, and it is expressed in cubic units of length in the SI system.
3. Recognize that the SI unit for length is the meter (m), so the SI unit for volume is the cubic meter, written as \(m^{3}\).
4. Note that the liter (L) is a commonly used unit for volume but is not an official SI base unit; however, it is accepted for use with the SI system and is equal to 1 cubic decimeter (\$1 L = 1 dm^{3}$).
5. Identify that among the options given, the liter (L) is the unit commonly used to measure volume in practical contexts, even though the SI derived unit is the cubic meter.
