Mathematics

V= 202.9 cm^3

Step-by-step explanation:

Let M be the mass, hence the density r is given by

$r=\frac{M}{V}$

where V is the volume. By isolating the volume, one has

$V=\frac{M}{r}$

By substituying the values

M=712.04 gr and r=3.51 $\frac{gr}{cm^3}$

one has

$V=\frac{712.04}{3.51} cm^3 \\V= 202.86 cm^3$
