An icebox made of 1.5cm thick styrofoam has dimensions `60cmxx60cmxx30cm`.It contains ice at `0^(@)C` and is kept in a room at `40^(@)C`. Find the rate at which the ice is melting. Latent heat of fusion of ice`=3.36xx10^(5)J kg^(-1)` . and thermal conductivity of styrofoam `=0.04Wm^(-1)C^(-1)` .

Explanation

To solve the problem step by step, we will follow these instructions:

### Step 1: Calculate the total surface area of the icebox.
The dimensions of the icebox are given as:
- Length (L) = 60 cm = 0.6 m
- Breadth (B) = 60 cm = 0.6 m
- Height (H) = 30 cm = 0.3 m
