Parameterize the ellipsoid using the augmented spherical coordinates:

Then the Jacobian for the change of coordinates is

which has determinant

Then the volume of the ellipsoid is given by

where 

 denotes the spaced contained by the ellipsoid. In particular, we have the definite integral and volume
 
 
        
        
        
Make bototm number same
3/10 times 13/13=39/130
4/13 times 10/10=40/130
A. 
39/130 and 40/130
they are 1/130 apart
B. 
a ratioal number between
39/130=390/1300
40/130=400/1300
between 390/1300 and 400/1300
any number from 391/1300 to 399/1300 example 395/1300
