[AI-generated answer — Bot GPT 3.5]

The radius of the cylinder is half of the diameter, so the radius is 14/2 = 7 meters.

The lateral surface area of the cylinder is given by the formula 2πrh, where r is the radius and h is the height.
So the lateral surface area of the cylinder is 2(3.14)(7)(12) = 527.52 square meters.
The base of the cylinder is a circle with radius 7 meters, so the area of one base is given by the formula πr^2.
So the area of one base of the cylinder is (3.14)(7^2) = 153.86 square meters.
Since there are two bases, the total area of both bases is 2(153.86) = 307.72 square meters.
Therefore, the surface area of the cylinder is 527.52 + 307.72 = 835.24 square meters. Answer: \boxed{835.24}.
