To find the height of the model, we first need to determine how many feet are represented by each inch in the model. Given the scale of 3.5 inches = 225 feet, we can start by calculating the number of feet per inch.

1. **Find feet per inch**:
\[
\text{Feet per inch} = \frac{225 \text{ ft}}{3.5 \text{ in}} \approx 64.2857 \text{ ft/in}
\]

2. **Determine the height of the model**:
We know the actual building is 900 feet tall. To find the height of the model in inches, we use the conversion factor we just calculated:

\[
\text{Model height in inches} = \frac{\text{Actual height}}{\text{Feet per inch}} = \frac{900 \text{ ft}}{64.2857 \text{ ft/in}} \approx 14 \text{ in}
\]

Therefore, the height of the model is approximately **14 inches**.
