30. 25. A glass cube of dimensions 10 cm x 10 cm x 4 cm
and weight 8 N rests with its sides 10 cm x 10 cm in
contact with top of a table. Calculate the pressure
exerted. If the cuboid is tilted and allowed to rest
on the surface on side 10 cm x 4 cm, will the
pressure increase, decrease or remain the same?
(Ans. 800 Pa, Pressure increases by 2.5 times)
31. how to do it in a sequence
