Physical: the raft needs to float, which means what you make the raft out of must be less dense than water.
The raft would need sturdiness- if the raft is frail, the water might break it
Chemical: It can not react with water and it can not be made of a completely soluable substance (something that would dissolve in it like salt)
Power = Voltage * Current
Substitute the known values,
P = 120 * 4
P = 480 W
In short, Your Answer would be: 480 Watts
Hope this helps!
