# Find the volume of an irregular shaped object?

You use integration - you divide the object into lots of thin layers, and calculate area x thickness for each. If the area is irregular, you use integration once again for each: divide it into lots of thin strips, and treat each as a rectangle. Wiki User

Either divide into several regular shaped objects and then sum the volumes

Or immerse in water. The volume it displaces is equal to its volume

immerse the object in a liquid where it floats.the weight of the object can be found by archimede's principle:

mass of the object*g=Volume of the liquid displaced(Vl)*density of the liquid(dl)*g

Also mass of an object = Volume of the object (Vo)*density of the object (do)

Thus the volume of the object = Vl*dl/do   Wiki User

This is Archimedes way. Fill a measuring cup with water. Then put your object in. Find how much the water volume increased. There. In a math test though, I can't help you.   Earn +20 pts
