How deep is the Pacific Ocean?

Deeper than the swimming pool.

take a dive and you shall see

very very deep

The deepest point in the ocean is the Mariana Trench located in the Pacific Ocean near the Northern Mariana Islands. It has a maximum depth of 10,923 m (35,838 ft) [2]. It was fully surveyed in 1951 by the British naval vessel, "Challenger II" which gave its name to the deepest part of the trench, the "Challenger Deep".

so, about 7 miles at the lowest point

It's deepest point is the Mariannas trench at 10,911 feet below the surface.
