Answer:
684 feet²
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
