Homework Statement
Find the mass of the rectangular box B where B is the box determined by
0 [tex]\leq[/tex] x [tex]\leq[/tex] 1, 0 [tex]\leq[/tex] y [tex]\leq[/tex] 2, and 0 [tex]\leq[/tex] z [tex]\leq[/tex] 1, and with density function [tex]\rho[/tex] ( x, y, z ) = z e^{x+y}.
Homework Equations
"u" substitution
The Attempt at a Solution
I believe I've taken the first integral with respect to dz correctly which led me to this integral
[tex]\int[/tex] from 0 to 1 [tex]\int[/tex] from 0 to 2 (1/2)e^(x+y) dy dx
I know i need to use a "u" substitution and have u=x+y but I'm unsure of how that changes the range of the integral with respect to y. if my equation is unclear please let me know. thank you!
