The ocean covers about 71% of the Earth’s surface. If the total surface area of the Earth is about 510 million square kilometers, how many square kilometers are covered by the ocean?
The ocean is 362.1 million square kilometers
Right.
To find the square kilometers covered by the ocean, you need to calculate 71% of the total surface area of the Earth.
Step 1: Calculate 71% of the total surface area of the Earth.
- Convert 71% to a decimal by dividing by 100: 71/100 = 0.71
- Multiply the total surface area of the Earth by 0.71: 0.71 * 510 million square kilometers = 362.1 million square kilometers
Therefore, the ocean covers approximately 362.1 million square kilometers of the Earth's surface.
