Answer:
344
Step-by-step explanation:
First we are going to find the area of the top and bottom
8x8=64. Since the top and bottom are the same, we can do 64x2=128.
Now we are going to find the area of the left and right sides.
8x7=54. Since the right and left are the same, we can do 54x2=108.
Now we are going to find the area of the front side and the back side.
8x7=54. Since the front and back are the same, we can do 54x2=108.
Now we add our answers up. 128+108+108=344
