To find the height of the popcorn box modeled as a right rectangular prism, we can use the formula for the volume of a rectangular prism:

\[
V = l \times w \times h
\]

where:
- \( V \) is the volume,
- \( l \) is the length,
- \( w \) is the width,
- \( h \) is the height.

We are given the following:
- Volume \( V = 35 \) cubic inches,
- Length \( l = 22 \) inches,
- Width \( w = 2.5 \) inches (since one half is 0.5, and \( 2 + 0.5 = 2.5 \)).

Now we can substitute the given values into the volume formula and solve for \( h \):

\[
35 = 22 \times 2.5 \times h
\]

First, calculate \( 22 \times 2.5 \):

\[
22 \times 2.5 = 55
\]

Now we can rewrite the equation:

\[
35 = 55 \times h
\]

To solve for \( h \), divide both sides by 55:

\[
h = \frac{35}{55}
\]

Simplifying that fraction:

\[
h = \frac{7}{11} \approx 0.63636 \text{ inches}
\]

Now rounding to the nearest tenth:

\[
h \approx 0.6 \text{ inches}
\]

Thus, the height of the popcorn box is approximately:

\[
\boxed{0.6} \text{ inches}
\]
