In Problems 1-3, use triple iterated integrals to find the indicated quantities.
1. Volume of the solid in the first octant bounded by y = 2x2 and y + 4z = 8
2. Volume of the solid in the first octant bounded by the elliptic cylinder y2 + 64z2 = 4 and the plane y = x
3. Volume of the solid bounded by the cylinders x2 = y and z2 = y and the plane y = 1
