Hello!

Ive been staring at this task for hours and would really appreciate if someone had a look at this:

Calculate:

∭ z dV

k

where k is the area which is limited by the surfaces :

x= 0

y= 0

z=0

x+y=1

x+y-z=0

I dont understand how the area looks and which "limits" to set!

Thanks in advance.
