10cm2
the surface area = 22 sq. inches
Find the area to one side of one of the cubes and multiply it by 18
If many smaller cubes are combined to form a larger cube, then the surface area of the large cube is: 6 x (length of one side squared)
(surface area of cube 1 or 2 (either)) times 2 = (total surface area of two identical cubes)
