Subject: GCSE Coursework (Number Grid Investigation),3D cubes rule I despereatley need

I have just finished my first year of teaching mathematics and at the end 
of this year,I set my year 10 (set 1) GCSE Mathematics group,their first 
peice of coursework,the number grid investigation (in the aqa syllabus -
Module 4).In this particular coursework you have to multiply the corners 
of number grids and try to find a pattern and find a formula in the 
diifference of the two ansewers.I have already got the formula for 
squares and rectangles but I am stuck on 3D cubes and reallly need this 
formula,so that when my students come back after the summer I can help 
them to find the formula.Because it's needed to get an A/A* grade in 
their coursework,which for top set students I feel they're capable of.I 
would really appreciate help,guidnace and the formaula if possibe.

Yours Sincerely
Jamie
