A cylindrical tube, open at both ends, is made of metal. The internal diameter of the tube is 10.4 cm and its length is 25cm. The thickness of the metal is 8mm everywhere. Calculate the volume of the metal.

Explanation

To find the volume of the metal in the cylindrical tube, we will follow these steps:

### Step 1: Identify the given dimensions
- Internal diameter of the tube = 10.4 cm
- Length (height) of the tube (h) = 25 cm
- Thickness of the metal = 8 mm

### Step 2: Convert the thickness from mm to cm
