Answer:
110.94
Step-by-step explanation:
Surface area is the area of each side of the shape added together. So in this situation, it would be the area of a side, multiplied by 6, because a square has six sides.
To find the area, it's length x width. You're given the length and width, which both are 4.3 mm.
4.3 x 4.3 = 18.49
With this new number, you're gonna multiply it by 6. And the total will be 110.94 mm. :)
