The volume \( V \) of a cube can be calculated using the formula:
\[
V = a^3
\]
where \( a \) is the edge length of the cube.
Given that the edge length \( a \) is 2.5 ft, we can calculate the volume as follows:
\[
V = (2.5)^3 = 2.5 \times 2.5 \times 2.5
\]
Calculating that step-by-step:
1. \( 2.5 \times 2.5 = 6.25 \)
2. \( 6.25 \times 2.5 = 15.625 \)
So, the volume of the cube is:
\[
V = 15.625 \, \text{ft}^3
\]
Rounded to the nearest thousandth, the volume is:
\[
\boxed{15.625 \, \text{ft}^3}
\]
