Final answer:
If 15,700,000 km³ of ice melted into the ocean, the global sea level would rise by approximately 80.74 meters, after converting the volume of water released from the melted ice to the sea level rise over the given surface area of the ocean basin.
Step-by-step explanation:
To calculate how much global sea level would rise if 15,700,000 km³ of ice melted, we first determine how much water is released when the ice melts. Given that the volume of water is 0.9 times the volume of ice, we multiply 15,700,000 km³ by 0.9, resulting in 14,130,000 km³ of water. To find the rise in sea level, we divide this volume by the surface area of the ocean basin. Using the given surface area of 175,000,000 km²:
Sea Level Rise = Volume of Water Released / Surface Area of the Ocean Basin = 14,130,000 km³ / 175,000,000 km² = 0.08074285714 km.
Since 1 kilometer equals 1,000 meters, we convert this number into meters:
Sea Level Rise = 0.08074285714 km * 1000 m/km = 80.74285714 m.
Therefore, if 15,700,000 km³ of ice were to melt, the global sea level would rise by approximately 80.74 meters.
