We can define density as the mass per unit volume;
D = M/V
here density is given that is 19.3g/cm³
and dimensions are given that is volume = 4.72 cm x 8.21 cm x 3.98 cm = 154.23 cm³
Now from the formula'
M = D x V
putting the values of density and volume
Mass = M = 19.3g/cm³ x 154.23 cm³ = 2976.64 g
