A cube of mass 1 kg and volume `125cm^2` is placed in an evacuated chamber at `27^@C`. Initially temperature of block is `227^@C`. Assume block behaves like a block body, find the rate of cooling of block if specific heat of the material of block is `400 J//kg-K`.

Explanation

To solve the problem step by step, we will follow the outlined approach based on the information given in the question.

### Step 1: Identify the given data
- Mass of the block, \( m = 1 \, \text{kg} \)
- Volume of the block, \( V = 125 \, \text{cm}^3 \)
- Initial temperature of the block, \( T_i = 227 \, \text{°C} \)
- Temperature of the chamber, \( T_0 = 27 \, \text{°C} \)
- Specific heat of the material, \( c = 400 \, \text{J/kg·K} \)
