What is the SI unit of 'volume'?
Cubic metre
The correct answer is Cubic metre.
The SI unit of volume is the cubic metre (m³). While litres (L), millilitres (mL), and cubic centimetres (cm³) are commonly used units of volume, they are not SI base units. The SI system prioritizes the metre (m) as the base unit of length, and volume, being a three-dimensional measurement of space, is derived from the cube of the metre, hence m³. Other units are often convenient for specific applications but the cubic metre remains the standard SI unit for volume.
