height =3.5m
=350cm
external diameter=2.4cm
therefore radius=1.2cm
width =2mm
therefore inner radius=1.2-2=1cm
volume of pipe(hollow)=π(R square-r square) height where r=inner radius and R=outer radius
=22/7(1.2 sq-1sq)350
=22(0.44)50
=484 cm cube
weight of 1 cm cube=10
therefore weight=484×10
=4840(unit not mentioned)
hope you got it pls mark it as brainliest
