To find the volume of a cube, you can use the formula:

\[ V = s^3 \]

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

In this case, the edge length is 5 and one half inches, which can be expressed as a mixed number:

\[ s = 5 \frac{1}{2} = 5.5 \quad \text{or} \quad s = \frac{11}{2} \text{ inches} \]

Now we will calculate the volume:

\[ V = \left(\frac{11}{2}\right)^3 = \frac{11^3}{2^3} = \frac{1331}{8} \text{ cubic inches} \]

Now simplify or convert if necessary:

To do the division, \( 1331 \div 8 = 166.375 \), which can be expressed as:

\[ V = 166 \frac{3}{8} \text{ cubic inches} \]

Thus, the volume of the cube is:

\[ \frac{1331}{8} \text{ cubic inches} \]

or

\[ 166 \frac{3}{8} \text{ cubic inches} \]

Final Answer:

The volume of the cube is \( \frac{1331}{8} \) cubic inches or approximately \( 166.375 \) cubic inches.
