To determine the height of the square pyramid using the Pythagorean theorem, we can use the relationship involving the height, the slant height, and half the length of the base.

Given:
- \( w \) (the width of the square base) = 40 ft
- \( s \) (the slant height) = 25 ft

1. First, we find half the width of the base:
\[
\text{Half base} = \frac{w}{2} = \frac{40}{2} = 20 \text{ ft}
\]

2. Now, we apply the Pythagorean theorem. In a right triangle formed by the height of the pyramid (h), half the base (20 ft), and the slant height (25 ft), we have:
\[
s^2 = h^2 + \left(\frac{w}{2}\right)^2
\]
Plugging in the values we have:
\[
25^2 = h^2 + 20^2
\]
\[
625 = h^2 + 400
\]

3. Subtract 400 from both sides:
\[
h^2 = 625 - 400 = 225
\]

4. Take the square root of both sides:
\[
h = \sqrt{225} = 15 \text{ ft}
\]

So the height of the square pyramid is **15.0 ft**.

Yes, let's double-check the calculations step-by-step to ensure accuracy:

Given:
- Width of the square base (w) = 40 ft
- Slant height (s) = 25 ft

1. **Calculate Half the Width of the Base**:
\[
\text{Half base} = \frac{w}{2} = \frac{40 \text{ ft}}{2} = 20 \text{ ft}
\]

2. **Apply the Pythagorean Theorem**:
We use the right triangle formed by the height (h), half the base (20 ft), and the slant height (25 ft):
\[
s^2 = h^2 + \left(\frac{w}{2}\right)^2
\]
Plugging in the values:
\[
25^2 = h^2 + 20^2
\]
This becomes:
\[
625 = h^2 + 400
\]

3. **Rearranging the Equation**:
Subtract 400 from both sides:
\[
h^2 = 625 - 400 = 225
\]

4. **Taking the Square Root**:
\[
h = \sqrt{225} = 15 \text{ ft}
\]

So, the height of the square pyramid is indeed **15.0 ft**. If this was the only information to base the calculations on, then yes, the result is correct. If there were any additional specifications or corrections, please let me know!

I appreciate your patience! Let's go through it one more time in detail to ensure everything is correct.

### Given:
- Width of the square base, \( w = 40 \, \text{ft} \)
- Slant height, \( s = 25 \, \text{ft} \)

### Steps:

1. **Calculate Half the Width of the Base**:
\[
\text{Half base} = \frac{w}{2} = \frac{40}{2} = 20 \, \text{ft}
\]

2. **Apply the Pythagorean Theorem**:
We need to calculate the height \( h \) using the relationship:
\[
s^2 = h^2 + \left(\frac{w}{2}\right)^2
\]
Plugging in the values:
\[
25^2 = h^2 + 20^2
\]
\[
625 = h^2 + 400
\]

3. **Rearranging the Equation**:
\[
h^2 = 625 - 400
\]
\[
h^2 = 225
\]

4. **Taking the Square Root**:
\[
h = \sqrt{225} = 15 \, \text{ft}
\]

### Conclusion:
- The calculated height \( h \) of the square pyramid is **15.0 ft**.
