An ice box used for keeping eatables cool has a total wall area of `1m^2` and a wall thichness of 5.0 cm. The thermal cunductivity of the ice box is `K=0.01 J//m^@C`. It is filled with large amount of ice at `0^@C` along with eatables on a dfay when the temperature is `30^@C` The latent heat of fusion of ice is `334xx10^3 J//kg`. The amount of ice melted in one day is ( 1 day`=86,000s`)

Explanation

To solve the problem of how much ice melts in one day in an ice box, we can follow these steps:

### Step 1: Identify the given values
- **Thermal Conductivity (K)**: \(0.01 \, \text{J/m°C}\)
- **Total Wall Area (A)**: \(1 \, \text{m}^2\)
- **Wall Thickness (D)**: \(5.0 \, \text{cm} = 0.05 \, \text{m}\)
- **Temperature Difference (\(\Delta \theta\))**: \(30°C - 0°C = 30°C\)
- **Time (T)**: \(1 \, \text{day} = 86,400 \, \text{s}\)
