"how FAST",not fact.and yes,the bigger the ice,the longger it takes to melt.

Yes. The more surface area, the faster an ice cube of any size melts.
So shapes that are realtively flat, or oddly shaped with many sides would melt much faster.
This is because melting rate has to do with the speed at which the ice cube shifts to the same temperature as the surrounding environment. More surface area means that more heat will be be able to move from the air (because more air is touching ice surface) to the ice, in the same amount of time. Alternatively this also means that a body of water with more surface area would also freeze faster under cold conditions.

Yes. The amount of surface area would determine how quickly it would transfer heat (conduct?) . So the more surface area you can create the faster it should melt. However, you called it a cube, so a cube really has only one shape. The proper question would be "Does shape affect how fast a mass of ice melts?"

Yes it does. Melting occurs as heat is transferred from the surrounding environment to ice. The rate of heat transfer is proportional to the contact area across which heat transfer occurs. The greater the surface area of the ice cube, the faster it will melt (off course, this is assuming that you don't exactly mean a "cube", but any ice piece in general)

well if it is an ice CUBE it will have the same shape...a cube. But yes the more surface area the faster it will melt

Is fact a typo? do you mean fast. If the volume of the ice is the same, the shape with the greatest surface area will melt fastest.

my guess, without doing any math, is YES. Melting depends on the heat transfer, and heat transfer depends on the contact area. So, if you have two pieces of ice with the same mass, one that is regular (let's say, a sphere) and another that is irregular, with more contact area, the second one melts faster at the same conditions... heat transfer depends on the area/volume ratio... the piece with a higher A/V ratio will melt faster.

yes, the more surface area the ice has exposed to open air, the faster it will melt. for exmaple, crushed ice or snow will melt faster than a block or a cube.

I believe the thinner the cube, the faster it melts.
