# Use a double integral to find volume of solids ?

 HW Helper P: 2,616 Well this is one of those maths methods which are essentially superseded when you learn a more general way of getting the same answer. More specifically when you learn triple integrals and volume, you might not remember this particular method. But anyway, in this case, you have to make use of a general formula for evaluating volume bounded above by function f(x,y) and below by plane surface R. $$\iint_R f(x,y) dA$$. In this case, you can easily discern the height function f(x,y) using the equation of the solid. For limits, you should be able to see where lines parallel to the x and y axis would enter and exit the solid.
