To find the volume of a cube, you can use the formula:
\[ \text{Volume} = s^3 \]
where \( s \) is the side length of the cube.
Given that the side length \( s \) is 2.5 inches, we calculate the volume as follows:
\[ \text{Volume} = (2.5)^3 = 2.5 \times 2.5 \times 2.5 \]
Calculating step-by-step:
- \( 2.5 \times 2.5 = 6.25 \)
- \( 6.25 \times 2.5 = 15.625 \)
Thus, the volume of the cube is \( 15.625 \) cubic inches.
Now, rounding this to the nearest tenth, we get:
\[ \text{Volume} \approx 15.6 \text{ cubic inches} \]
So, the volume of the cube is approximately 15.6 cubic inches.
