Hameed has built a cubical water tank with lid for his house, with each other edge 1.5m long. He gets the outer surface of the tank excluding the base, covered with square tiles of side 25cm. Find how much he would spend for the tiles, if the cost of tiles is Rs. 360 per dozen.

Explanation

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

### Step 1: Calculate the Surface Area of the Cubical Water Tank
The formula for the surface area of a cube excluding the base is given by:
\[ \text{Surface Area} = 5 \times \text{edge}^2 \]
Given that the edge of the cube is 1.5 m, we can calculate:
