Given
We have a rectangular piece of metal
Or we can say cuboid who's dimensions are
L=3m=>300cm (1m=100cm)
B=1.5m =>150cm
H=3cm
Volume of cuboid piece=lxbxh
=300x150x3
=135000cm³
1cm³ weight =7g
Then weight of 135000cm³=135000x7
=945000g
=945kg (1kg =1000g)
This is ur ans hope it will help you in case of any doubt comment below

Length = 3m =300cm
Breadth= 1.5m = 150cm
Height = 3cm
Volume of cuboid = LBH
=300*150*3
=135000cm cube
1cm cube = 7g
135000cm cube = 135000*7g
=945000g
