Final answer:
To find the surface area of simple composite solids, you need to calculate the sum of the individual surface areas of the different components using the appropriate formulas for their shapes.
Step-by-step explanation:
The surface area of composite solids can be calculated by finding the sum of the individual surface areas of the different components. Each component's surface area can be determined using the appropriate formula for its shape. For example, for a cylinder, the surface area is the sum of the areas of the two circular bases and the curved surface. By applying the formulas for the different shapes and adding them together, you can find the surface area of a composite solid.
