Use the net to find the surface area of the prism.

684 feet²

Step-by-step explanation:

Since this net contains six rectangles, so we will find the area of all rectangles and add them to find the surface area of the prism.

Surface area of the prism = ( 8×9 + 15×9 + 8×9 + 15×9 + 15×9 + 15×9 )

72 + 135 + 72 + 135 + 135 + 135

= 684 feet²

The surface area of the prism is 684 feet²
