C. 336 cm²

Step-by-step explanation:

Area formulas:

-----------------------------------------------------------------------------------------------------------------

In this figure, there is a rectangle with a width of 12 and a height of 6.

; the area of the rectangle is 72 cm².

There are two right triangles with legs of 6 and 8.

There are two right triangles so..

The area of a single triangle is 24 cm²; the area of the triangles combined is 48 cm.

There is a rectangle in the middle with a width of 8 and a height of 12.

The area of the rectangle is 96 cm².

Lastly, there is a rectangle with a width of 10 and a height of 12.

The area of the rectangle is 120 cm².

Now, add the areas of every shape to find your answer.

Therefore, the surface area of this three-dimensional figure is 336 cm².
