Answer is: the volume of water after the solid is added is 4.5 ml.

d (gold) = 8.0 g/cm³; density of gold.

m (gold) = 4 g; mass of gold.

V (gold) = m (gold) : d (gold); volume of gold.

V (gold) = 4 g : 8 g/cm³.

V (gold) = 0.5 cm³ = 0.5 ml.

V (water) = 4.00 ml = 4.00 cm³.

V (flask) = V (gold) + V (water).

V (flask) = 0.5 cm³ + 4 cm³. V = 4.5 cm³.
