Consider the solid that lies above the rectangle (in the
xy-plane) R=[−2,2]×[0,2],
and below the surface z=x2−4y+8.
(A) Estimate the volume by dividing R into 4 rectangles of equal
size, each twice as wide as high, and choosing the sample points to
result in the largest possible Riemann sum.

Set up a triple integral for the volume of the solid that lies
below the plane x + 2y + 4z = 8, above the xy-plane, and in the
first octant.
Hint: Try graphing the region and then projecting into the
xy-plane. To do this you need to know where the plane
x+ 2y + 4z = 8 intersects the xy-plane (i.e. where z = 0).
Find the volume of the solid obtained by revolving the region
