To find the volume of the right rectangular prism packed with 8 cubes, we first need to calculate the volume of one cube.
The volume \( V \) of a cube can be calculated using the formula:
\[ V = \text{edge length}^3 \]
Given that the edge length of each cube is 15 centimeters:
\[ V = 15 , \text{cm} \times 15 , \text{cm} \times 15 , \text{cm} = 15^3 , \text{cm}^3 = 3375 , \text{cm}^3 \]
Since there are 8 cubes, the total volume of the rectangular prism (which is equal to the volume of the 8 cubes) is:
\[ \text{Total Volume} = 8 \times 3375 , \text{cm}^3 = 27000 , \text{cm}^3 \]
Thus, the volume of the rectangular prism packed with 8 cubes is:
\[ \text{Volume} = 27000 , \text{cubic centimeters} \]
Since none of the provided responses list 27000 cubic centimeters, please double-check the options or provide more context for accuracy.
