Expert Answer:

Dear Student,

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.
