R

be the region in the first quadrant bounded by

x=y

and

x=y^{2}

. A solid has base

R

, and cross sections perpendicular to the

y

-axis are right isosceles triangles whose hypotenuse lies in

R

. What is the volume of the solid? a)

\dfrac{1}{60}

\dfrac{1}{30}

\dfrac{1}{120}

\dfrac{\sqrt{3}}{120}
