To rearrange the formula for the volume of a box, \( V = lwh \), to solve for the width \( w \), you divide both sides by the product of the length \( l \) and the height \( h \):

\[
w = \frac{V}{lh}
\]

In this rearrangement, let's analyze the units of \( V \), \( l \), \( h \), and \( w \):

- Volume \( V \) is measured in cubic inches (in³).
- Length \( l \) is measured in inches (in).
- Height \( h \) is measured in inches (in).

Thus, the units for \( lh \) (length times height) are:

\[
l \times h = \text{in} \times \text{in} = \text{in}^2
\]

When you divide \( V \) (in³) by \( lh \) (in²), the units become:

\[
\frac{V}{lh} = \frac{\text{in}^3}{\text{in}^2} = \text{in}
\]

This means that the width \( w \) is measured in inches (in).

To justify our rearrangement with regard to units, we can express the relationship in a simple equation:

\[
\frac{\text{in}^3}{\text{in}^2} = \text{in}
\]

Among the given options, the best representation of the remaining units when justifying the rearrangement to solve for the width would be:

\[
\frac{i \cdot n^3}{i \cdot n^2} = in
\]

Thus, the conclusion is that the remaining units result in \( \text{in} \), which matches the units for width \( w \).
