An iron ball has an air space in it, the ball weights ong kg in air and O-6 kg in water. Find the volume of the air space. Density of iron is` 7200 kg m ^(-3)`.

Explanation

To solve the problem step by step, we will use the information provided about the iron ball, its weights in air and water, and the density of iron.

### Step 1: Understand the Given Data
- Weight of the iron ball in air, \( W_{air} = 1 \, \text{kg} \)
- Weight of the iron ball in water, \( W_{water} = 0.6 \, \text{kg} \)
- Density of iron, \( \rho_{iron} = 7200 \, \text{kg/m}^3 \)

### Step 2: Calculate the Loss of Weight in Water
