The volume below the surface z=sin(x)cos(y), above the xy-plane and inside the rectangle [0,pi/2]x[0,pi/2] is approximated by 8 slices, where the x-value has been held constant at the midpoint of each sub-interval (so x=pi/32, 3pi/32, ... , 15pi/32). This is an illustration of Fubini's Theorem and iterated integration.

This model pairs nicely with Volume: slices y constant and Volume: no slices. See http://www.thingiverse.com/thing:928463 and http://www.thingiverse.com/thing:928456.

This model was designed and printed by my WLU summer research student Ryan McDonnell ('17).
