Help, integral volume problem.

Let R be the region in the first quadrant enclosed by the y-axis and the graphs of y=sin x and y = cos x. Find the volume of the solid whose base is R and whose cross sections cut by planes perpendicular to the x-axis are rectangles where the width (which lies in the xy-plane) is one-third the length.
