Three containers have different area on the top surface and same base area. If equal volume of a liquid is put in them which will have more pressure at its base?

A sphere and a cube have equal surface areas.What is the ratio of the volume of the sphere to that of that cube?

If we interchange the lenths of the base and the height of a cuboid to get another cuboid, will its lateral surface area change?

If we interchange the lenths of the base and the height of a cuboid to get another cuboid, will its lateral surface area change?

A cylinder with a movable piston contains 3 moles of hydrogen at standard temperature and pressure. The walls of the cylinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume?

Find the radius of the sphere, if the rates of increase in its volume and surface area are equal.

Two vessels have the same base area but different shapes. The first vessel takes twice the volume of water that the second vessel requires to fill upto a particular common height. Is the force exerted by the water on the base of the vessel the same in the two cases? If so, why do the vessels filled with water to that same height give different readings on a weighing scale?

A ring and a circular disc of different materials have equal masses and equal radii. Which one will have a larger moment of inertia about an axis passing through its centre of mass perpendicular to its plane?

A cylinder,a cone and a hemisphere are of equal base and have the same height.What is the ratio of their volumes?

Two cubes have their volumes in the ratio 1:27.What is the ratio of their surface areas?
