Given, A solid cube is cut at middle to make two make two cuboids.
Let the side of the cube be a and it is cut at middle. So breadth of newly formed cuboids is (a/2), length isa, height is a.
Total surface area of cube=6a2
Total surface area of cuboids = Surface area of cuboid
=2(lb+bh+lh)=2(2a×a+a×a+2a×a)=4a2
Ratio of total surface area of cube to cuboid =4a26a2=3:2
