Choose the correct option: 

The cube is a special type of a ________, where l = b = h.

A cube is a special type of cuboid whose length, breadth and height, all dimensions are equal

In a cube, the total surface area = 6 l² where l is the side of a cube

In a cuboid, the total surface area = 2(lb + bh + lh), given l=b=h

= 2(lxl + lxl + lxl)

= 2(3l²) = 6l²

We can say that the total surface area of a cube is equal to the total surface area of a cuboid.

Similarly, the lateral surface area and volume of the cube and cuboid are the same.

Therefore, A cube is a special type of cuboid whose length, breadth and height, all dimensions are equal.
