Some points: The melting 'ice' is not in the water, but in the continents (Greenland, Antarctica, etc.), thus it is additive. The thermal expansion of ocean water needs to be considered. The layer of water (ocean) is just that, a layer of about 3 Km in thicknes. Try working with an annulus model & you will find a more accurate value for sea level rise.
All of these are approximations though, as the ocean is not truly a layer covering earth - just accounting for ~ 3/4 of said surface. Furthe more the shoreline is not vertical & that beach/gradual incline will temper some of the sealevel rise. All of these can be shown with simple tools - in a water filled tray, using clay to simulate land of various 'shoreline forms', just add ice originating from land. It's fun too.
