mass over volume
The volume of an irregularly shaped solid can be measured by placing the solid in a known quantity of water in a container with measurement markings. Take the new volume and find the difference between this and the old volume. This is the volume of your irregularly shaped solid.
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 measure the density of an irregularly shaped solid using water displacement, you can submerge the solid in a known volume of water and measure the volume of water displaced. Then, divide the mass of the solid by the volume of water displaced to find the density. Since the solid may not displace water as neatly as a regular shape, it's important to take accurate measurements and ensure the solid is fully submerged.
Geometry, or algebra (integration).
You measure its mass and volume and then density = mass/volume.
When you are trying to find the volume of an irregularly shaped object.
Liquid displacement
lenght x weight x height
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.
V= Base Area * Height
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.
