Given the value of \( n = 9 \), let's calculate the value of each cube in the pyramid.

### Bottom Row:

1. **Left Cube:** \( 3n - 2 = 3(9) - 2 = 27 - 2 = 25 \)
2. **Middle Cube:** \( 7 \) (already given)
3. **Right Cube:** \( 10 \) (already given)

### Middle Row:

1. **Left Cube (x):** We previously found \( x = 175 \). This was calculated using the equation \( x = (3n - 2) \times 7 \), which we already solved.
   
   \[
   x = 25 \times 7 = 175
   \]

2. **Right Cube (y):** We also previously found \( y = 70 \). This was calculated using the equation \( y = 7 \times 10 \).

   \[
   y = 7 \times 10 = 70
   \]

### Top Cube:

- **Top Cube:** The value at the top is given as \( 12250 \), which was found by multiplying the middle cubes \( x \) and \( y \):

  \[
  12250 = 175 \times 70
  \]

### Summary of Values:

- **Bottom Row:** 25, 7, 10
- **Middle Row:** 175, 70
- **Top Row:** 12250

Here are five related questions you might consider:

1. What would happen if the top number was different? How would it affect the values below?
2. How do we approach a similar problem if one of the middle numbers is unknown?
3. Can you find a general formula for the top number based on the bottom row values?
4. What if the pyramid had an additional row? How would the calculations change?
5. How could you verify your answers using another method?

**Tip:** Double-check your intermediate calculations, especially in problems involving multiple steps, to avoid errors that could affect the final result.
