What is the density of the bird statue?

[xoxjojobxox]

Homework Statement

An antique yellow statuette of a bird is suspended from a spring scale. The scale reads 11.81 N when the statuette is suspended in air, and it reads 11.19 N when the statuette is completely submerged in water.
a. Find the volume of the statuette
b. Is the bird made of gold? (ρ=19.3 x 10³ k/m³g)
or gold-plated aluminum? (ρ=2.7 x 10³ k/m³g)

Homework Equations

ρ(density)=m/v (mass/volume)
F_T+F_b=F_g
F_g=mg
