Answer Question 1 (iii). "DO NOT SEND ANY LINKS".
Edge of the Cube = 6cm
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
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
