To find the volume of the right rectangular prism packed with 8 cubes, we first calculate the volume of one cube. The volume \( V \) of a cube is given by the formula:
\[ V = \text{edge length}^3 \]
Each cube has an edge length of \( \frac{1}{5} \) centimeter. Therefore, the volume of one cube is:
\[ V = \left( \frac{1}{5} \right)^3 = \frac{1}{125} \text{ cubic centimeters} \]
Since there are 8 cubes, the total volume of the prism is:
\[ \text{Total volume} = 8 \times \frac{1}{125} = \frac{8}{125} \text{ cubic centimeters} \]
So, the final answer is:
\[ \frac{8}{125} \text{ cubic centimeters} \]
The correct response is:
8/125 cubic centimeters.
