The volume \( V \) of a right rectangular prism is calculated using the formula:
\[ V = \text{length} \times \text{width} \times \text{height} \]
For the given dimensions:
- Length = 25 inches
- Width = 15 inches
- Height = 5 inches
Now, substituting the values into the formula:
\[ V = 25 , \text{inches} \times 15 , \text{inches} \times 5 , \text{inches} \]
Calculating step-by-step:
-
First, calculate \( 25 \times 15 \): \[ 25 \times 15 = 375 \]
-
Next, multiply that result by the height (5 inches): \[ 375 \times 5 = 1875 \]
Thus, the volume of the box is:
\[ \boxed{1,875} \text{ cubic inches} \]
