ANSWERLength of the resulting cuboid 4+4+4=12cmHeight and breadth remain same as 4cmTotal surface area of a cuboid of length l, breadth b and height h.=2(l×b+b×h+l×h)

ANSWERLength of the resulting cuboid 4+4+4=12cmHeight and breadth remain same as 4cmTotal surface area of a cuboid of length l, breadth b and height h.=2(l×b+b×h+l×h)So, the total surface area of this cuboid =2(12×4+4×4+12×4)=224cm
