How do you calculate the density of a solid object?

You calculate the density of a solid object by dividing its mass by its volume.

To calculate the density of a solid object, you need to know two things: the object's mass and its volume. The mass of an object is a measure of how much matter it contains. This can be measured using a balance or scales. The volume of an object is a measure of how much space it occupies. For regular shaped objects, you can calculate the volume using mathematical formulas. For example, the volume of a cube is calculated by cubing the length of one of its sides (length x length x length). For irregular shaped objects, you can measure the volume by displacement of water in a measuring cylinder.

Once you have these two measurements, you can calculate the density using the formula: Density = Mass ÷ Volume. The units of density are typically grams per cubic centimetre (g/cm³) or kilograms per cubic metre (kg/m³).

For example, if you have a solid cube that has a mass of 20g and each side measures 2cm, you would first calculate the volume. The volume of a cube is side³, so in this case, it would be 2cm x 2cm x 2cm = 8cm³. Then, you would divide the mass by the volume to find the density. So, 20g ÷ 8cm³ = 2.5g/cm³. This means the density of the cube is 2.5g/cm³.

Remember, density is a property of the material itself, not the size or shape of the object. So, no matter how big or small the object is, if it's made of the same material, it will have the same density.
