The **mass formula** states that mass (m) is calculated as the product of an object’s density (ρ) and its volume (v). Mathematically, the formula for mass is expressed as m = ρ × v. This formula enables the calculation of the mass of an object based on its density and volume.

## Practice problems

### Problem #1

Calculate the mass of a steel object if the density of steel is 8050 kg/m^{3} and the volume of the object is 0.012 m^{3}.

**Solution**

Given data:

- Mass of the object, m = ?
- Density of steel, ρ = 8050 kg/m
^{3} - Volume of the object, v = 0.012 m
^{3}

Applying the formula:

- m = ρ × v
- m = 8050 × 0.012
- m = 96.6 kg

Therefore, the mass of a steel object is **96.6 kg**.

### Problem #2

If the density of a diamond is 3510 kg/m^{3} and the volume of the diamond is 0.005 m^{3}, then calculate the mass of the diamond.

**Solution**

Given data:

- Density of a diamond, ρ = 3510 kg/m
^{3} - Volume of a diamond, v = 0.005 m
^{3} - Mass of a diamond, m = ?

Applying the formula:

- m = ρ × v
- m = 3510 × 0.005
- m = 17.55 kg

Therefore, the mass of a diamond is **17.55 kg**.

### Problem #3

The density of silver is 10497 kg/m^{3} and the volume of the silver object is 0.008 m^{3}. Calculate the mass of the silver object.

**Solution**

Given data:

- Density of silver, ρ = 10497 kg/m
^{3} - Volume of the object, v = 0.008 m
^{3} - Mass of the object, m = ?

Applying the formula:

- m = ρ × v
- m = 10497 × 0.008
- m = 83.97 kg

Therefore, the mass of a silver is **83.97 kg**.

### Problem #4

Find the mass of a block of ice with a density of 917 kg/m^{3} and a volume of 0.007 m^{3}.

**Solution**

Given data:

- Mass of ice block, m = ?
- Density of block, ρ = 917 kg/m
^{3} - Volume of block, v = 0.007 m
^{3}

Applying the formula:

- m = ρ × v
- m = 917 × 0.007
- m = 6.41 kg

Therefore, the mass of an ice block is **6.41 kg**.
