Hey mate here is your ans..
Here, mass of the box, m=2.3kg
Mass of one gold piece, m 1
=20.15g=0.02015kg
Mass of other gold piece, m 2
=20.17g=0.02017kg
∴ Total mass = m+m 1 +m 2
=2.3kg+0.02015kg+0.02017kg=2.34032kg
As the result is correct only upto one place of decimal, therefore, on rounding off, we get Total mass =2.3kg
the difference in the masses of the pieces t
= 0.02017kg-0.02015kg
=0.0002kg
