Question

_______ is the space occupied by one unit of an object

Answer 1

1. The space occupied by an object is called Volume.
2. Volume of an object can be calculated by unit volume method; unit volume is defined as space occupied by one unit of an object.
3. Volume of small unit of an object = $a^{\mathit{3}}$, where $\mathit{\text{'}}a\mathit{\text{'}}$ is the length of each sides of the cube
4. if N number of units contained in an object then,
   $volume\mathit{}of\mathit{}an\mathit{}object\mathit{}\mathit{=}{a}^{\mathit{3}}\mathit{\times }N\mathit{}$

Thus, volume is the space occupied by one unit of an object.
