Volume of the block of Zirconium=`(8.55*2.40*1.04)` ` cm^3`

=`21.3408` `cm^3`

We know that Density=Mass/Volume

Zirconium has a density of `6.52` `gcm^-3`

Hence, its Mass=Density*Volume

=`(6.52*21.3408)` g

=`139.142` g

=`(139.142/1000)` Kg

=`0.139142` Kg.

Therefore, the mass of the block of Zirconium is 0.139142 Kg.
