It's a trick question.
Calculate the volume of the tub.
Now calculate the volume of the ice ball. Remember the ice floats and has a lower density than water. The ice when melted, will have a slightly smaller volume than as an ice ball.
If you had to calculate to the end, you'd calculate the "lost volume" of ice as it melted, convert it to water volume, and determine depth in the tub.
That's enough hints. "Nothing to it but to do it" (I used to have a teacher that said that)
