The surface area of the composite shape is determined as 150 m².

How to calculate the surface area of the composite shape?

The surface area of the composite shape is calculated by applying the following formula as shown below;

We will start from top to the bottom of the composite solid.

Total surface area = (3 m x 2 m ) + 2 ( 3 m x 9 m) + 2 (9m x 2 m) + (5m x 2 m) + (8m x 2 m) + 2 (5 m x 2 m) + 2 (2 m x 2 m)

So we will evaluate the total surface area as follows;

Total surface area = 6 m² + 54 m² + 36 m² + 10 m² + 16 m² + 20 m² + 8 m²

Total surface area = 150 m²

Thus, the surface area of the composite shape is determined as 150 m².
