A vessel in the shape of a cuboid contains some water. If three indentical spheres are immersed in the water, the level of water is increased by 2cm. If the area of the base of the cuboid is 160 `c m^2` and its height 12cm, determine the radius of any of the spheres.

Explanation

Let the radius of each sphere be` r `cm



Volume of a sphere `=(4/3πr^3) cm^3`



Increase in volume of the cuboid `=162×2 cm^2`
