A right pyramid has a unit square base ABCD and vertex V. Its height is 1 unit.
Points E and F are on CV and DV respectively such that ABEF is a plane section that splits the pyramid into two pieces of equal volume.
Find the length EF.
I just want to point out that a simple geometric solution is possible (I solved it using calculus before I realized it.)
