Question

There is a solid cube which has been cut into two cuboids of equal volumes. find the ration of the total surface area of one of the cuboids to that of the given

Answer 1

if cube of side s is cut into two cuboids of equal volumes
then the dimensions of cuboid are
length = s
breadth = s
height = s/2
total surface area of given cuboid = 2(lb+bh+hl)
                                                          = 2(s²+s²/2+s²/2)
                                                          = 4s²
total surface area of cube = 6s²
ratio = 4s²/6s² = 2:3
