The volume \( V \) of a right rectangular prism is calculated using the formula:
\[ V = \text{length} \times \text{width} \times \text{height} \]
Plugging in the values given:
\[ V = 6 \times 5 \times 8 \]
Calculating this step-by-step:
- \( 6 \times 5 = 30 \)
- \( 30 \times 8 = 240 \)
Thus, the volume of the right rectangular prism is 240.
