How is the total area of the world's oceans 361 million square kilometres? I can't see how the five individuals ones add to that.
When I Google how many squared km is this/that ocean, I get
When add the areas of those five oceans, 106.5+161.8+70.56+14.06+20.33
I get 373.25 million sq km.
Yet the world ocean, which should be the sum of the 5 oceans, is 361 million sq km.
If I try this site https://www.infoplease.com/world/world-geography/oceans-and-seas
It says Pacific = 155.557, Atlantic = 76.76, Indian = 68.556, Southern =2 0.327, Arctic = 14.056
155.557 + 76.76 + 68.556 + 20.327 + 14.056 = 335 sq km
So, also, not 361 million square km
Any idea why the figures differ and what are the correct figures?
