\begin{gathered} \text{volume of the rectangular prism=1x1x2=2} \\ \text{volume of the smal cube=1x1x1=1} \\ we\text{ can compare these volumes with the ratio:} \\ \frac{\text{volume of the rectangular prism}}{\text{volume of the small cube}}=(2)/(1)=2 \\ \text{hence, 2 small cube can be packed in the rectangular prism} \end{gathered}
\begin{gathered} \text{from the ratio, we can s}e\text{ that:} \\ \frac{\text{volume of the rectangular prism}}{\text{volume of the small cube}}=2\Rightarrow\text{volume of the rectangular prism}=2\cdot\text{volume of the small cube} \\ \text{that is, the volum of the rectangular prism is 2 times the volume of the unit (small) cube} \end{gathered}
