Answer 2

Step-by-step explanation:

Given A wire of 4 mm diameter is made by pulling a metallic cube whose side is 1 cm.  The length of the wire is  

• Given edge of cube = 1 cm
• Volume of cube = 1 cm^3 = 1000 mm^3
• Diameter of wire = 4 mm
• So radius will be 4/2 = 2 mm
• Now volume of wire = volume of cube
• So πr^2 h = 1000  
• So π x 2 x 2 x h = 1000
• Or h = 1000 / 4π
•        = 250 / π mm
• Or h = 25 / π cm
