For any cuboid with the volume 250 , the possible sides could be 5*5*10 or 25*5*2, the former works for us, cutting the longest side into 2 will give us cube of side 5.
Rest calculation is easy :
surface area of 2 square - 300
surface area of cuboid - 250
final answer- 50
Kudos if it helped anyone.
