Volume = 4/3*pi*radius3 = 900 cubic inches
By making the radius the subject of the above equation gives the sphere a radius of 5.989418137 inches.
Surface area = 4*pi*5.9894181372 = 450.7950449 square inches

0.4 m-1 is the ration of surface area 588m2 to volume 1372m3 for a sphere.
A globe is a sphere in which two mathematical formulae are used to calculate its surface area and its volume: Surface area of a sphere = 4*pi*radius2 in square units. Volume of a sphere = 4/3*pi*radius3 in cubic units.
Not necessarily. Having the same volume does not mean having the same surface area. As an example, if you were to take a sphere with volume 4/3*pi*r^3, and a suface area of 4*pi*r^2, and compare it to a cube with sides 4/3, pi, and 4^3, you would find that they had a different surface area, but the same volume. Let the radius of the sphere be 2, that is r = 2. In this case the surface are of the sphere is about 50, and the surface are of the cube is about 80. So a sphere and a cube, both with a volume of about 33.51 (4/3 * pi * 8), have different surface areas.
