Why does ice cubes with more surface area melt faster than ice cubes with less surface area?

i am doing a science fair project about ice cubes and the shape effecting how long the ice cube takes to melt. i just can't find the answer for this question.

So if the ice cube has a larger surface area, it will melt faster because of external factors such as radiation/heat affecting (directly) - as there is a larger area to penetrate. The water molecules in the ice are stretched out over a large surface area, therefore able to absorb more heat energy - if it is less dense as well as greater surface area.

= The more surface area an ice-cube has, the more energy it can absorb from the atmosphere, and the more quickly it can melt.

because more area of the ice cube will be exposed to the greater than freezing point degree...

Ice cubes with more surface area melt faster than ice cubes with less surface area due to increase in contact with the surrounding. Therefore, it absorbs more heat, making it melt faster as compared with the ice cubes that have small surface area.

Yeah, that's correct. A suggestion: measure how surface area is related to melting time, and find a model that explains that.
