Expert Answer:

Here, volume of cylinder = pi r2h
Let the water level rise by height h.
Volume space of space water space after space imerging space straight a space cube space equals space Volume space of space water space initially space plus space Volume space of space metal space cube
Therefore comma space volume space of space displace space water space equals space volume space of space cube
rightwards double arrow 22 over 7 cross times left parenthesis 10 right parenthesis squared cross times straight h equals 8 cubed
rightwards double arrow straight h equals 1.6 space cm
