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.

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

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.

To find the volume of an irregular object such as a rock, you have to use displacement. If you place the object in a graduated cylinder filled with water, the volume of the object is equal to the amount of water that the object displaces. For example, if a graduated cylinder is filled with 100mL of water, and you place an object such as a rock and the water rises from 100mL to 106mL, then the volume of the rock is 6.

Step 1) Fill the graduated cylinder with water to a specific volume (example: 50ml).Step 2) Drop the irregular shaped object into the graduated cylinder.Step 3) Measure the new level of the water in the graduated cylinder.Step 4) The difference in volumes in the graduated cylinder equals the volume of the irregular objectexample:original volume of water in cylinder = 50mlvolume of water in cylinder with irregular object = 55ml55ml - 50ml = volume of irregular object in the water = 5ml

There are many ways to find the volume of irregular shapes, but the most commonly used method is Water Displacement.

You do not need fancy lab equipment.Basically you need to determine two pieces of information1) The mass of the "irregular" shape (use a scale)2) The volume of the shape (use water displacement in a bucket/tub to find volume)Take the mass / volume and you have density.

you devide the mass of the object by the volume e.g. the mass of the block = 360g the volume = 120cm3 to find the density you divide 360 by 120 which = 3 to find the volume of a block you times the height by the width by the lenth eg 6 (L), 5(W), 4(H) = 6x5x4 = 120

Displacement method.... Is the method to find volume of an irregular object

Make a mold of the object and then fill the mold with water and measure the volume of the water.

Measure the volume of the object which is same as the volume of the displaced liquid in which that sinks. And measure the mass of the same object from a weighing machine. then use density = mass/volume

you put the shape into sections and find there volumes and add your answers together

1. fill the container with water (make sure you write down what you filled it to) 2. Place object into the container 3. Calulate how much the water rose 4. Find the difference of the two numbers (that will be you volume of the irregular shaped object) 5. All finished!!!

If the body is a solid not soluble in water then we can keep it immersed in a measurable jar. Just noting down the level of water raised and getting the difference in the level with the initial one, we can get the volume of the irregular shaped object.

Volume is the amount of cubic centimeters in an object. To find the volume of a regular shaped object multiply length x width x height. To find an irregular shaped objects volume put water in a container and measure the amount. Place the object in the water and measure the new volume. Subtract the old volume from the new volume and that's your answer. You would write as x cm3. Weight is gravity's pull on an object

It is a method called displacement. Displacement is a method that many scientists use. First you put a certain amount of water in a container (test tube, beaker). Second you Measure how many milliliters of water you put into it. Next you Add your irregular object into the water. Then you measure how many milliliters the water level rose. Then you subtract your second measurement with the irregular shaped object in it by your first measurement without the object in it and it will give you the volume of your irregular shape object.
