Inner Diameter of the tube= 12 cm
Thickness of the tube = 1cm
Density of metal =7.8 g/cm3
Cross section area of of metal tube = [ (12+1) 2 - 12 2 ] = 25 sq cm
Length of the tube = 1m=100 cm.
Volume of the metal = Crosection area of tube X Length = 25 X 100 = 2500 cm 3 .
Weight of the tube= metal volumeX Density
= 2500 X 7.8= 19500 g= 19.5 Kg.
