To find the volume of a right rectangular prism (box-shaped container), you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
Given the dimensions:
- Length = 7.5 feet
- Width = 5 feet
- Height = 3 feet
Plugging in the values:
\[ \text{Volume} = 7.5 , \text{ft} \times 5 , \text{ft} \times 3 , \text{ft} \] \[ \text{Volume} = 7.5 \times 5 = 37.5 \] \[ \text{Volume} = 37.5 \times 3 = 112.5 , \text{ft}^3 \]
Therefore, the volume of the container is 112.5 ft³.
So the correct response is:
112.5 ft.³
