1. **State the problem:** Find the surface area of a right hexagonal prism with side length of the hexagon $s=3$ cm, height $h=9$ cm, and given edges 6 cm on the lower edges (which correspond to the apothem or other dimensions).
2. **Formula for surface area of a right prism:**
$$\text{Surface Area} = 2 \times \text{Base Area} + \text{Lateral Area}$$
where the lateral area is the perimeter of the base times the height.
3. **Calculate the base area:**
The base is a regular hexagon with side length $s=3$ cm.
The area of a regular hexagon is given by:
$$\text{Base Area} = \frac{3\sqrt{3}}{2} s^2$$
Substitute $s=3$:
$$\text{Base Area} = \frac{3\sqrt{3}}{2} \times 3^2 = \frac{3\sqrt{3}}{2} \times 9 = \frac{27\sqrt{3}}{2}$$
4. **Calculate the perimeter of the base:**
A hexagon has 6 sides, so:
$$\text{Perimeter} = 6 \times s = 6 \times 3 = 18$$
5. **Calculate the lateral area:**
$$\text{Lateral Area} = \text{Perimeter} \times h = 18 \times 9 = 162$$
6. **Calculate total surface area:**
$$\text{Surface Area} = 2 \times \text{Base Area} + \text{Lateral Area} = 2 \times \frac{27\sqrt{3}}{2} + 162 = 27\sqrt{3} + 162$$
7. **Final answer:**
$$\boxed{27\sqrt{3} + 162 \text{ cm}^2}$$
This is the total surface area of the hexagonal prism.
