Answer Question 1 (iii). "DO NOT SEND ANY LINKS".

Area of the cube = 6³ = 216 cm³

As the cube is melted to make a cuboid,

Area of cube = Area of cuboid

i.e, Area of cuboid = 216 cm³

Now,

It is given that

length of the cuboid = 12cm

breadth = 6cm

Therefore,

Area of a cuboid = lbh

lbh = 216 cm³

12 x 6 x h = 216

h = 216/12 x 6

h = 3 cm
