1. Step-by-step explanation:

   Let the side of one cube = a

   Surfaces area of resulting cuboid = 2(Total surface area of a cube) – 2(area of single surface)

   We know that,

   Total surface area of cube = 6a² , where a = side of cube

   ⇒ Surfaces area of resulting cuboid = 2(6a²) – 2(a²) = 10a²

   Also, According to the question,

   Volume of cube = 64 cm³

   Volume of cube = a³

   64 = a³

   a = 4 cm

   Therefore, Surface area of resulting cuboid = 10a² = 10(4)2 = 160 cm²
