Final answer:

The surface area of the rectangular solid is 478 cm².

Step-by-step explanation:

To find the surface area of a rectangular solid, you need to calculate the area of each face and then add them together. The formula for the surface area of a rectangular solid is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.

Using the given measurements of 7 cm, 9 cm, and 11 cm for the sides, we can plug them into the formula:

Surface Area = 2(7)(9) + 2(7)(11) + 2(9)(11)

Surface Area = 126 + 154 + 198

Surface Area = 478 cm²
