We can use the formula for density to calculate the mass of the object:
Density = Mass / Volume
Rearranging the formula, we get:
Mass = Density x Volume
Substituting the given values of density and volume, we get:
Mass = 657 g/mL x 32 mL = 21,024 g
Therefore, the mass of the object is 21,024 g or 21.024 kg (rounded to three decimal places).
