Question

A cube of 9 CM age is immersed completely in a rectangular vessel containing water at the dimensions of base 15 and 12 find the rise in the water level in the vessel

Answer 1

let the increase in height = h
volume of cube = volume of water risen
⇒9³ = 15*12*h
⇒ h = 9³/(15*12)
⇒ h = 4.05 cm -------rise in water level
