In a cylindrical jar with a bottom area S, the height of the water is H = 15 cm. When an empty brass cup (density of brass RL = 8.8 g/cm3) was lowered into this jar so that it floated, the water in the jar rose by h = 2, 2 cm. What will be the height H1 of the water level in the jar if the cup is drowned in it?
