A brick measures 12 cm `xx` 6 cm `xx` 3 cm. Initially, it is kept on the ground such that the rectangular surface with the smallest area is in contact with the ground and then it is placed such that the rectangular surface with the largest area touches the ground. Calculate the height of the centre of gravity from the ground in the two cases. Out of the two positions, in which case does the brick have greater stability and why?

Explanation

(i) In first case
Height of the brick = 12 cm
Height fo CG from the ground = 6 cm
(i) In second case
Height of the brick = 3 cm
Height of CG from the ground = 1.5 cm
In the second case the brick has more stability because height of CG is small and also base area is more.
