How many square miles are the oceans?
139 million square miles
Oceans cover approximately 70.8% or 361 million square kilometers (139 million square miles) of Earth’s surface (Table 8o-1) with a volume of about 1370 million cubic kilometers (329 million cubic miles). The average depth of these extensive bodies of sea water is about 3.8 kilometers (2.4 miles).
How is the ocean calculated?
The most common and fastest way of measuring ocean depth uses sound. Ships using technology called sonar, which stands for sound navigation and ranging, can map the topography of the ocean floor. The device sends sound waves to the bottom of the ocean and measures how long it takes for an echo to return.

What is the equation to calculate ocean depth?
Answer: Use the following formula for measuring ocean depth. D = V Times 1/2 T D = Depth (in meters) T= Time (in seconds) V = 1507 m/s (speed of sound in water) Calculate the depth foe each of the times given below, using the formula above.
What is the length of Pacific Ocean?
The Pacific Ocean stretches from the Bering Strait to 60° S latitude through more than 120° of latitude, nearly 9,000 miles (about 14,500 km).

Which is the correct formula for calculating square miles?
Or, if you’ve been given the space’s area in a different unit of measure, you can convert from that unit into square miles. Apply the formula A = l × w for any rectangular-shaped area, where A is the area, l is the area’s length in miles and w is its width in miles.
How big is the area of the oceans?
“… approximately 360 million square kilometers (140 million square miles), or 71 percent, are represented by the oceans and mariginal seas.”.
How to calculate the area of a lake?
Divide by 5,280 to convert your measurements in (linear) feet into miles. So if you are calculating the area of a lake that measures 5,280 feet by 10,560 feet, you’d divide each measurement by 5,280: 5280 ÷ 5280 = 1. 10560 ÷ 5280 = 2. So the area measures 1 mile by 2 miles.
How do you calculate the area of a square?
If the diagonal of a square is given, then the formula to calculate the area of a square is: A = (½) × d 2 square units. Where “d” is the diagonal What is the perimeter and the area of a square?
