A piece of brass of volume `30 cm^3` has a mass of 252 g. Find the density of brass in `kg m^(-3)`

Explanation

To find the density of brass, we will follow these steps:

### Step 1: Convert mass from grams to kilograms
The mass of brass is given as 252 grams. To convert grams to kilograms, we use the conversion factor that 1 kg = 1000 g.

\[ \text{Mass in kg} = \frac{252 \text{ g}}{1000} = 0.252 \text{ kg} \]
