How many cubic centimetres (cm3) are in a cubic metre (m3)?

Result
Your answer: —  ·  Correct: B
Explanation

To determine the number of cubic centimetres (cm³) in a cubic metre (m³), one must consider the linear relationship between the two units. One metre is equal to 100 centimetres. Since volume is a three-dimensional quantity, the conversion factor must be cubed: (100 cm)³ = 100 × 100 × 100 cm³. This calculation results in 1,000,000 cubic centimetres. In scientific notation, 1,000,000 is expressed as 10⁶. Therefore, 1 m³ is equivalent to 10⁶ cm³. This conversion is essential in various scientific and engineering fields to translate measurements between the standard SI unit of volume (m³) and smaller scales (cm³). The other options, such as 10³ (1,000) or 10⁹ (1,000,000,000), do not correctly represent the cubic relationship of the base units.
