The radius of a sphere of lead (B = 4.2 x 101°N/m?) is 1.000 m on the surface of the earth where the pressure is 1.01×10⁵ N/m² .The sphere is taken by submarine to the deepest part of the ocean to a depth of 1.10 x 10⁴ m where it is exposed to a pressure is 1.25×10⁸ N/m². What is the volume of the sphere at the bottom of the ocean? the answer is 4.176m³
