Working in Cartesian coordinates 
, and 
, select a volume element 
. (There are six possible choices: 
, 
, 
, 
, 
, 
.)
Enter an integrand and the appropriate bounds of integration.
Compute the value of the integral either exactly or numerically.
Obtain a graph of the 3-D region determined by the limits of integration. The bounding faces for the region of integration are drawn with the following color-coding: ![(∫)[yellow]^(gray)(∫)[green]^(brown)(∫)[blue]^(red)Psi ⅆv](/support/helpjp/helpview.aspx?si=3986/file05362/math73.png)
