how could i determine the volume of an object that had an irregular shape? (i can’t measure it with a ruler)

a boat has a mass of 19 000 000kg and a volume of 45 000m3. would this boat sink or float in water? prove your answer mathematically.

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,[tex]p_{w}=1000kg/m^3[/tex]

Density,   [tex]p = \dfrac{m}{V}[/tex]

Mass of boat=19,000,000

Volume of boat=45,000[tex]m^3[/tex]

[tex]p_{b}=\frac{19,000,000kg}{45,000m^3}\\p_{b}=422.22kg/m^3[/tex]

[tex]p_{w}>p_{b}[/tex]

Therefore the boat will float on water.
