Answer:
The volume of an irregular shape can be found by placing it in a can (of known volume) of water. The amount of water the shape displaces is equal to its volume.
Boat will float. It has a lower density that that of water.
Step-by-step explanation:
If an object has a lower density than the fluid it is in, it will float. If higher, it will sink.
Assuming the water is at room temperature:
Density of water,
Density,
Mass of boat=19,000,000
Volume of boat=45,000
Therefore the boat will float on water.
