Does the shape of an ice cube affect the rate at which the ice cube will melt?

Well, an ice cube melts because it absorbs heat from the atmosphere and
the solid water molecules start moving faster (See our human atoms
demo). The outer surface of the ice cube absorbs the heat and it starts
melting first. The amount of heat an ice cube could absorb would depend
on its surface area.
In case you haven't taken geometry, surface area is the total area
of all the surfaces of an object. The more surface area an icecube has,
the more energy it can absorb from the atmosphere, and the more quickly
it can melt
