How to calculate mass

 To calculate mass, you can use the formula:

$$Mass=Density×Volume

Where:

• Mass is the amount of matter in an object, typically measured in kilograms (kg) or grams (g).
• Density is the density of the material the object is made of, measured in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).
• Volume is the amount of space occupied by the object, measured in cubic meters (m³) or cubic centimeters (cm³).

Simply multiply the density of the material by the volume of the object to find its mass. If you have an irregularly shaped object, you can measure its volume by methods like displacement (submerging it in water and measuring the displaced water) or using appropriate formulas depending on its shape.

Keep in mind that the units should be consistent. For example, if you're using density in g/cm³, make sure the volume is in cm³ to get mass in grams. If you need the mass in kilograms, convert accordingly (1 kg = 1000 g)
