Find the volume of the tetrahedron with vertices $(0,0,0), (0,0,1), (1,0,1), (0,1,1)$, equation $$x+y=z$$
bounded by $x=0$, $y=0$ and $z=1$.



Then $x+y=1$. My integral: is this correct?
$$int_0^1 int_0^z int_0^z-y ,dx,dy,dz$$

Your limit are correct, considering the YZ axis, if you want another example to understand better I have given the limits considering the XZ plane.



The tetrahedron is having it's base on the XZ plane and YZ plane so it will be a good idea to consider the limits from the XZ plane to the $x+y=z$ plane.



considering the limits from the YZ plane to the $x+y=z$



$y=0$ to $y=z-x$



Now as the limits for the volume has been take care of the area formed on the XZ plane is considered.
If the strip is considered paralled to the z axis then the limits



$z=x$ to $z=1$ and the limits of the x are $x=0$ to $x=1$ . This limit has been chosen to make it easier to solve the last integral using the Beta function.



The equation will be
$$int_0^1int_x^1int_0^z-xdy dz dx$$
