As shown in a figure, there is a cube whose length of one side is 5 cm and EP is parallel to BC.
The difference of the total surface area of two solids which are made by cutting this cube with the plane which passes along four point A, E, F, and D was 42 cm2.
In this case, find the length of BE.
Answer
