A marble (B = 70 GPa)statue of volume 1.0 m³ is being transported by ships from Athens to Cyprus. The statue topples into the ocean when an earthquake-caused tidal wave sinks the ship; the statue ends up on the ocean floor, 1.0 km below the surface. Find the change in volume of the statue in cm³ due to the pressure of the water! The density of seawater is 1020 kg/m³. Use g = 10 m/s².

• 110 cm³

• 145 cm³

• 220 cm³

• 290 cm³

• 15 GPa

• 1.5 GPa

• 60 GPa

• 6 GPa
