The formula for the volume \( V \) of a cube is given by:

\[
V = s^3
\]

where \( s \) is the length of one edge of the cube.

For a cube with an edge length of \( 2.5 \) ft, the volume can be calculated as follows:

\[
V = (2.5 \, \text{ft})^3
\]

Calculating \( (2.5)^3 \):

\[
(2.5)^3 = 2.5 \times 2.5 \times 2.5
\]

First, calculate \( 2.5 \times 2.5 \):

\[
2.5 \times 2.5 = 6.25
\]

Next, multiply by \( 2.5 \) again:

\[
6.25 \times 2.5 = 15.625
\]

Thus, the volume of the cube is:

\[
V = 15.625 \, \text{ft}^3
\]

Rounding to the nearest thousandth:

\[
V \approx 15.625 \, \text{ft}^3
\]

Therefore, the volume of the cube is:

\[
\boxed{15.625} \, \text{ft}^3
\]
