The question presents a square-based pyramid with a square base \( ABCD \) where the side length \( AC = 30 \, \text{cm} \), and the height \( T \) from the base to the apex is \( 17 \, \text{cm} \).

### Step-by-step solution:

1. **Find the side length of the square base:**
   Since \( ABCD \) is a square and \( AC \) is the diagonal, we use the Pythagorean theorem for the square:
   \[
   AC = \sqrt{AB^2 + BC^2}
   \]
   Let the side of the square be \( s \). The diagonal \( AC \) is:
   \[
   AC = s\sqrt{2}
   \]
   Given \( AC = 30 \, \text{cm} \), we solve for \( s \):
   \[
   30 = s\sqrt{2}
   \]
   \[
   s = \frac{30}{\sqrt{2}} = 15\sqrt{2} \, \text{cm}
   \]

2. **Calculate the area of the base:**
   The area \( A \) of the square base is:
   \[
   A = s^2 = (15\sqrt{2})^2 = 450 \, \text{cm}^2
   \]

3. **Calculate the volume of the pyramid:**
   The volume \( V \) of a pyramid is given by:
   \[
   V = \frac{1}{3} \times \text{base area} \times \text{height}
   \]
   Substituting the known values:
   \[
   V = \frac{1}{3} \times 450 \times 17 = \frac{1}{3} \times 7650 = 2550 \, \text{cm}^3
   \]

4. **Check if the shape has four pyramids sharing the same base:**
   This would divide the volume by 4:
   \[
   V_{\text{final}} = \frac{2550}{4} = 637.5 \, \text{cm}^3
   \]

The final result should be cross-checked with the multiple choices; however, I might have made a misstep, considering this initial conclusion, and I will check against clearer
