I want to understand what knowing "the sum of 3 sides of a 3-d rectangular box" means.
The question was from my job interview. I didn't really understand what they meant but later, I just had an idea that the company is an organization for a fulfilment warehouse business and they need to calculate for the right box to contain items.
After the interview, I went to the company's website and they were saying the cover boxes to contain items are selected by the sum of 3 sides of a 3-d rectangular box. What is a value of a side, here?
----------------------------------------------------Updated------------------------------------------------------
But by knowing the sum of 3 sides of a 3-d cover box, how do we know an item can be contained in the a bigger 3-d box?
----------------------------------------The way I have understood ------------------------------------------
They say "the sum of 3 sides" and my understanding of the sum of 3 sides is that each side has its own length and each side of the cover box must be bigger than the item case, otherwise the item cannot fit in the cover box.
Can somebody tell me what it means? and I am not sure the way I interpret is correct or not.
Can you please be more clear ? are you sure that it is the sum of the three sides of the rectangle rather than the sum of the square of the three sides ?
The sum of the sides of the rectangle is l + b + h,
square root of the square of three sides ie $ \sqrt {l^2 + b^2 + h^2} $ gives the dimension of the diagonal which gives a fair idea of the maximum length of an object that can be placed diagonally into the box.
Look at the image below
d is the length of the diagonal and it is the maximum length of the object that the box can accommodate.
