diamonds and math... formula for length

[marv117]

ok...this is a weird question..but I've forgotten my math ..hehe...i wanna find out the diagonal lenth inside a square. As some of you may have read in my other post, I am planning to buy a princess cut, a square. Dimensions is always given so all we need is the formula to get the length inside....

I do remember, however, that a square can be made into two triangles. so we can use a formula for a triangle also...so this means we would be looking for the base length of the triangle...for example... dimensions given:
6.05(lenth) x 5.95(width) x 3.95...etc...

Correct me if I'm wrong but princess cut with the same carat and length/width of a round cut, the princess cut may look larger because of the corners...right?

Just something I noticed after looking at diamonds...thanks for the help!


----------------- UPDATE -----------------
I FOUND THE FORMULA!
Pythagorean Theorem : a² + b² = c²
'C' being the longest length of the triangle.
'A' and 'B' can be the length or the width of a square given dimension.

I found it here:

and here is an online calculator for this formula:
