Density of a substance is defined as its mass per unit volume. Mathematically,

`D=M/V`

`rArr M=D*V`

Given that lead has a density of 11.4 g/mL. Taking 3.45 L, i.e. 3.45*10^3 mL of lead, the mass can be obtained by putting the values of D and V in the above equation.

Thus,

`M=11.4*(3.45*10^3)g`

`=39330 g`

`=39.33 kg`

Therefore, the mass of the statue is 39.33 kilograms.
