The volume \( V \) of a cube can be calculated using the formula:

\[
V = s^3
\]

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

Given that the edge length \( s = 18 \) inches, we can substitute this value into the formula:

\[
V = 18^3
\]

Calculating \( 18^3 \):

\[
18^3 = 18 \times 18 \times 18
\]

First, calculate \( 18 \times 18 \):

\[
18 \times 18 = 324
\]

Now multiply that result by 18:

\[
324 \times 18
\]

Breaking it down:

\[
324 \times 18 = 324 \times (10 + 8) = 3240 + 2592 = 5832
\]

Thus, the volume of the cube is:

\[
V = 5832 \text{ cubic inches}
\]

So, the volume of the cube is \( \boxed{5832} \) cubic inches.
