The external diameter of a lead pipe is `2.4 cm` and the thickness of the lead is `2 mm.` Find the weight of a pipe of length `7 m`, it being given that `1 cm^3` of lead weight `10 g.`

Explanation

To find the weight of the lead pipe, we will follow these steps:

### Step 1: Convert the thickness of the lead from mm to cm.
The thickness of the lead is given as `2 mm`. We need to convert this to centimeters:
\[ \text{Thickness} = 2 \text{ mm} = \frac{2}{10} \text{ cm} = 0.2 \text{ cm} \]
