Question
Consider the right tetrahedron cut from the first octant (i.e. x ≥ 0, y ≥ 0,
and z ≥ 0 and the plane 6x + 4y + 2z = 12.
1. Solve for z in the equation of the plane to obtain the “top” formula for
the integral. Because the solid is cut on the bottom by z = 0 (since it's cut
from the first octant), the "bottom" formula will be z = 0.
2. Sketch the projection (“shadow") of the solid onto the xy-plane. This
should be a 2d graph. Number the axes appropriately and shade in the
region.
3. Use the graph and your answer from #1 to express the volume of the solid
as a triple integral.
4. Evaluate your integral from #2 to find the volume of the tetrahedron.
