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
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
