Hi,

I am making a program in Excel to find the optimum box size. i know to get the box size you need to ^volume 1/3 and then you round it up, but this dose not give the optimum box size all the time as it would need to be a multiple of 5 or 10. So this means i need to work out the length, width and height. but i cannot find the formula. Please can some help me?

Many Thanks
