milliliters
The volume of an ice chest can vary widely based on its size and design. Ice chests typically range from small cooler bags holding about 5 liters (5,000 milliliters) to large, heavy-duty coolers that can hold 100 liters (100,000 milliliters) or more. To determine the exact volume in milliliters, you would need to check the specific capacity of the ice chest you have in mind.
The answer depends on the scale: it could be millilitres, or litres, or cubic metres, or cubic kilometres.
Heat must have to be applied to the ice cube.
A sea water ice cube would melt faster than a normal ice cube because sea water has a lower freezing point due to the presence of salt. This means that it would require less heat energy to melt the sea water ice cube compared to a normal ice cube.
That would depend on the temperature of the cube and the water along with the volume of water and the mass of the ice cube and its area.
a ice cube in alcohol would melt fastest because of the heating molecules contracting with the ice cube molecules
if you were to add water an ice cube an olive oil the water would be on the bottom and the oil would be on top and the ice cube wuld float inside of the olive oil.
Size is irrelevant. An ice cube can be any size, so long as it is frozen from a liquid state in its container (remember, liquids fill their containers). However, a standard-size ice cube from a tray is 1.2 cubic inches (roughly--the cubes usually slope slightly, changing their volume). Also, their size depends on how much water you place in the tray before freezing.
It means 4 and 1/3 liters of liquid: juice, lemonade, milk, ice cream, ext.
The ice cube in contact with other materials has somewhere to pass it's energy to. The ice cube in isolation retains it's heat as the heat has nowhere to disperse to.

It depends on the size of the ice cube. Some are long and some are short.But why would you need to know that?
