The volume of the substance is its physical property that requires a space to occupy. The volume of 12.0 m³ is equivalent to 1.2 × 10¹⁰ mm³. Thus, option C is correct.
What is volume?
Volume is said to be the three-dimensional estimation of the space occupied by any matter. The volume can be measured by the molar concentration, density, length, breadth, etc.
The SI unit estimates and expresses volume in cubic meters (m³), and the CGS unit used is cubic centimeter (cm³).
Converting 12.0 m³ to km³ as:
1000 m = 1 km
12.0 m³ = 12.0 × 10⁻⁹ m³
Hence, option A. 1.2 × 10⁻³ km³ is incorrect.
Converting 12.0 m³ to mm³ as:
1 m = 1000 mm
12.0 m³ = 1.2 × 10¹⁰ mm³
From this conversion, it can be said that option B. 1.2 × 10⁴ mm³ is incorrect.
Therefore, option C. 1.2 × 10¹⁰ mm³ is equivalent to 12.0 m³.
