There are two cuboids with the surface area of 12cm and 178, and the cuboid with the surface area of () cm and 178;

A: (20)
If the surface area of cube is 12cm ^ 2, then the area of each face is 12 / 6 = 2
If the side length of a cube is a, then a ^ 2 = 2
Two cubes form a cuboid, with two faces coincident
So: the surface area of the cuboid = 12 + 12-2a ^ 2 = 24-4 = 20cm ^ 2
So: the surface area of the cuboid is 20cm ^ 2
