The capacity of a closed cylindrical vessel of height 1m is 15.4 litres. How many square metres of metal sheet would be needed to make it?

Explanation

To solve the problem step by step, we need to find the total surface area of a closed cylindrical vessel given its height and capacity. Here’s how we can do it:

### Step 1: Convert the volume from liters to cubic centimeters
1 liter is equivalent to 1000 cubic centimeters. Therefore, we convert the given volume:
\[ 15.4 \text{ liters} = 15.4 \times 1000 = 15400 \text{ cm}^3 \]
