How long would it take for an ice sculpture to melt completely into a puddle of water?

How long would it take for an ice sculpture to melt completely into a puddle of water? The original dimensions were 40"x20"x10" shaved into a Minnie Mouse with a head of 20"x20" and a base of 20"x20"? Obviously, this would be a good estimate...days/hours/minutes?? Thanks so much.
