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.
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
One way to find the volume of a large irregular shape object is to use the displacement method. Submerge the object in a container of water and measure the volume of water displaced. This volume is equal to the volume of the irregular object.
water displacement
To calculate the density of an irregular shaped floating object, you can measure its mass using a balance and then find its volume by submerging it in a known volume of water and measuring the water displaced. For a regular shaped floating object, you can simply divide its mass by its volume to find the density.
To find the density of a regular shaped object, you can calculate it by dividing the mass of the object by its volume. For irregular shaped objects, you would measure the mass of the object using a scale, then measure its displaced water volume when submerged in a graduated cylinder. The density can then be calculated by dividing the mass by the volume of water displaced.
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.
One way to measure the volume of an irregular shaped object is by using the water displacement method. Submerge the object in a known volume of water and measure the increase in water level, which is equal to the volume of the object.
There is no general formula. Many times an object can be looked at as the sum of smaller parts for which a formula is known. Ultimately all shapes can be reduced to small polyhedrons and then summed.
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
To find the volume of an irregular-shaped solid object, you can use a method called displacement. Fill a container with water, then submerge the object in the water and measure the amount of water displaced. The volume of the object is equal to the volume of water displaced, which can be calculated using the formula for volume of a regular shape.
To calculate the mass of an irregular shaped object, you can use a scale to measure its weight and then convert this to mass using the acceleration due to gravity. To find the volume of the object, you can use methods like water displacement or geometric calculations depending on the shape of the object.
