Answer 1

Given
Weight of 1cm³ wooden block=0.5g

Now we have length, breath and height of another block

So volume of that block=lxbxh

=10x8x4=320cm³

If 1cm³ wooden block's weight =. 5g

Then weight of 320cm³ block =320x.5

=320x1/2=160g

This is ur ans hope it will help you

The volume of a wood = 10×8×4
