Answer:
382
Step-by-step explanation:
surface area of a cube can be solved by finding the area of each side then adding everything together.
8*9= 72
8*7= 56
7*9= 63
Because in this prism, the sides are just doubled, you can just multiply each solution above by 2.
72*2= 144
56*2= 112
63*2= 126
Add all the solutions together after doubling them
144+112+126= 382
