volume of 150 spheres = volume of cylindrical rise in water
4/3*22/7*1.4/2*1.4/2*1.4/2*150 = 22/7*7*7*height
4*0.7*0.7*0.7*50=3.5*3.5*height
68.6/12.25=height
height = 5.591cm
4/3*22/7*1.4/2*1.4/2*1.4/2*150 = 22/7*7*7*height
4*0.7*0.7*0.7*50=3.5*3.5*height
68.6/12.25=height
height = 5.591cm

Hi
We have two radius and we have to find height
so,
Vol. of sphere *150 = Vol. of cylinder
By solving it, the answer is 5.56cm
