The area of a square can be calculated with this formula:
Where "s" is the length of any side of the square.
In this case, you can observe in the figure that:
Therefore, substituing that value into the formula, you get that the area of any of the cube's faces is:
Finally, in order to find the surface area of the cube, you need to multiply the area of a face calculated above, by 6.
Therefore, the surface area of the design is:
