**MathMate**, Sunday, May 13, 2012 at 4:20pmVolumes of pyramids above the cutting planes are proportional to the cube of the height.

So the volume above the cutting plane at h/4 is

V1=(3/4)^3*100=2700/64 in³

Volume above the 2h/3 cut is

V2=(1/3)^3*100=100/27 in³

The volume between two cuts are therefore

= V1-V2

=100(27/64-1/27)

=16625/432

=38.48 in³ (approx.)
