Inner Diameter of the tube= 12 cm
Inner Radius of the tube = 6 cm
Thickness of the tube = 1 cm
Outer Radius of the tube = 6 + 1 = 7 cm
Density of metal =7.8 g/cm3
Cross section area of of metal tube = π[72 - 62 ] = 40.82 sq cm
Length of the tube = 1 m=100 cm.
Volume of the metal = Crosection area of tube X Length = 40.82 X 100 = 4082 cm3 .
Weight of the tube= metal volumeX Density
= 4082 X 7.8 = 31839.6 g = 31.8 kg
