Which of the following is the SI base unit for volume?

• A. gallon (gal)
• B. liter (L)
• C. cubic meter (m^3)
• D. milliliter (mL)

Answer: (C)

Verified step by step guidance

1. Understand that the SI base units are the fundamental units defined by the International System of Units for measuring physical quantities.
2. Recall that volume is a measure of the amount of space an object occupies, and it can be expressed in terms of length units cubed.
3. Identify the SI base unit for length, which is the meter (m). Since volume is length cubed, the SI base unit for volume is the cubic meter, written as \(m^{3}\).
4. Recognize that other units like liter (L), milliliter (mL), and gallon (gal) are derived or customary units for volume but are not SI base units.
5. Conclude that among the options given, the cubic meter (\(m^{3}\)) is the correct SI base unit for volume.
