A cylindrical jar is 20 cm high with internal diameter 7 cm.
find the volume of the cylinder / cm
h=20, radius =3.5cm
volume = pi*(3.5)^2*1
= 22/7 *3.5*3.5*1
=38.5 cm^3
Change in volume of water is the volume of cube.
volume of cube = 5^3 = 125 cm^3
38.5 cm^3 = 1 cm height of jar
125 cm^3 = ?
125/38.5
=3.25 cm

An iron cube of edge 5 cm is immersed completely in the water which was originally 12 cm high ,present in the jar.find the rise in the level of the water.
