The volume of a right rectangular prism can be calculated using the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
In this case:
- Length = 8 meters
- Width = 10 meters
- Height = 5 meters
Calculating the volume:
\[ \text{Volume} = 8 , \text{m} \times 10 , \text{m} \times 5 , \text{m} = 400 , \text{m}^3 \]
Therefore, the units that express the volume of the right rectangular prism are cubic meters (m³).
