I sketched the region and got the following limits..
for x--- x=0 to x=6(1-y)
for y- - - y=0 to y=1
for z----z= 0 to z= 7(1-x/6-y)
i evaluated the integral with the order of integration dzdxdy (Everything is correct up to here!) and i got 15 but it's wrong.
can someone explain me if my bounds or order of integration are wrong,
thank you
