Find the volume of the solid under the plane 3x+2y−z=0 and above the region enclosed by the parabolas y=x^2 and x=y^2.
Yuri [45]

The region in the <em>x</em>-<em>y</em> plane is the set of points

R=\{(x,y)\mid0\le x\le 1,x^2\le y\le\sqrt x\}

The height of the solid falls between the <em>x</em>-<em>y</em> plane (for which <em>z</em> = 0) and the equation of the plane, <em>z</em> = 3<em>x</em> + 2<em>y</em>.

So the volume is

\displaystyle\int_0^1\int_{x^2}^{\sqrt x}\int_0^{3x+2y}\mathrm dz\,\mathrm dy\,\mathrm dx

=\displaystyle\int_0^1\int_{x^2}^{\sqrt x}(3x+2y)\mathrm dy\,\mathrm dx

=\displaystyle\int_0^1(3x^{3/2}+x-3x^3-x^4)\,\mathrm dx

=\displaystyle\frac65+\frac12-\frac34-\frac15=\boxed{\dfrac34}
