To find the total surface area of the figure, we need to calculate the sum of the surface areas of all the individual rectangles.

Surface area of 4 cm x 6 cm = 4 cm x 6 cm = 24 cm²
Surface area of 4 cm x 18 cm = 4 cm x 18 cm = 72 cm²
Surface area of 6 cm x 4 cm = 6 cm x 4 cm = 24 cm²
Surface area of 6 cm x 12 cm = 6 cm x 12 cm = 72 cm²
Surface area of 4 cm x 6 cm = 4 cm x 6 cm = 24 cm²
Surface area of 2 cm x 6 cm = 2 cm x 6 cm = 12 cm²

Total surface area = 24 cm² + 72 cm² + 24 cm² + 72 cm² + 24 cm² + 12 cm² = 228 cm²

Therefore, the total surface area of the figure is 228 cm².
