1. The problem statement, all variables and given/known data Estimate the volume of the solid whose base is bounded by the graphs of y = x + 3 and y = x2 − 3, and bounded by the surface z=x2+y from above, using the indicated rectangular cross sections taken perpendicular to the x-axis (figure is not the actual graph of the functions given above. It is solely a demonstration to help with the problem). 2. Relevant equations 3. The attempt at a solution I've been trying to figure out a way to solve it for hours. The only thing that i've done was figure out the area of the base, but i don't know if I am on the right track or not, seeing as the professor has not gone over this.
