To calculate the surface area, we need to find the lateral surface area of each cylinder and the area of the rectangular shape in between.
Surface Area of Cylinder = 2πrh
= 2 * 3.14 * 15 * 18
= 1,701.6 yards^2 (for 1 cylinder)
Total surface area for both cylinders = 1,701.6 * 2 = 3,403.2 yards^2
Area of the rectangle = l * w = 18 * 15 = 270 yards^2
Total surface area including the rectangle = 3,403.2 + 270 = 3,673.2 yards^2
Therefore, the closest option is 3,108.6 yards^2.
