# Volume of a solid limited by two paraboloids

Volume of a solid limited by these two paraboloids z=$$2x^2{}$$+$$y^2{}$$ and z=12-$$x^2{}$$-$$2y^2{}$$

hi can someone help me? I tried to solve this and my solution was $$\ 24$$$$\Pi$$ is it correct? can someone solve this step by step?

I am assuming you are in calculus. In this case you would find the intersection of these two functions, and integrate the difference of the two functions over the areas.

How did you get your result of 24 pi? Show us what you did and we'll help you with it.

BTW, you should have posted this in the Calculus & Beyond section, not the Precalculus Math section.
