The problem asks to find the surface area of a cube, where the side length of the cube is given as 9 yards.

### Formula for the surface area of a cube:
The surface area \( A \) of a cube is calculated as:
\[
A = 6 \times s^2
\]
where \( s \) is the length of one side of the cube.

### Given:
- \( s = 9 \, \text{yd} \)

Now, let's compute the surface area.

\[
A = 6 \times (9)^2 = 6 \times 81 = 486 \, \text{yd}^2
\]

So, the surface area of the cube is **486 square yards (yd²)**.

Would you like more details or further explanation?

Here are 5 related questions to expand on this:
1. What would the surface area be if the side length of the cube was doubled?
2. How do you calculate the volume of a cube, and what would the volume be for this cube?
3. What is the difference between surface area and volume for three-dimensional shapes?
4. How does the surface area of a cube compare to the surface area of other rectangular prisms with the same volume?
5. What is the relationship between the side length and the surface area of a cube?

**Tip**: Always check the units in geometry problems to ensure you're calculating and reporting the correct dimensions.
