Verified step by step guidance

1. Step 1: Understand what volume means in chemistry. Volume is the amount of space that a substance or object occupies, and it is measured in cubic units or units derived from cubic measurements.
2. Step 2: Identify the units given in the problem: liter, milliliter, kilogram, and cubic meter.
3. Step 3: Recognize that liter (L) and milliliter (mL) are common units of volume, where 1 liter equals 1000 milliliters.
4. Step 4: Recognize that cubic meter (m\^3) is a standard SI unit of volume, representing the volume of a cube with edges of 1 meter.
5. Step 5: Understand that kilogram (kg) is a unit of mass, not volume, so it does not measure the amount of space occupied.
