To find the width \( w \) of the rectangular prism, we can use the formula for the volume:

\[
V = lwh
\]

We are given:

- Volume \( V = 90 \, \text{ft}^3 \)
- Length \( l = 3 \, \text{ft} \)
- Height \( h = 12 \, \text{ft} \)

We can rearrange the formula to solve for \( w \):

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

Now, substituting the known values into the formula:

\[
w = \frac{90}{3 \times 12}
\]

Calculating the denominator:

\[
3 \times 12 = 36
\]

Now, substituting this back into the equation for \( w \):

\[
w = \frac{90}{36}
\]

Now we can simplify:

\[
w = 2.5 \, \text{ft}
\]

Thus, the width is:

\[
\boxed{2.5}
\]
