Yes you have to use the pythagorean theorm to find the length of a right triangle. But you must subtract A2 from C2 then square root the answer.

Cool question ! Answer - half it then cube it to prove it - an example for you if cube diagonal (not square diagonal) is 100, then using pythagoras theorm the square diagonal = 70.71068, If square the square diagonal = 70.71068, then using pythagoras theorm the side length = 50 therefore the volume = 50 ^ 3 = 25000 units works with any numbers

You use the pythagorous theorm to calculate the hypotenuse of the triangle, which is the same line as the diagonal. 7(7)+ 10(10)= diagonal x diagonal 149= diagonal x diagonal Diagonal= square root of 149: this approximates to 12.207in Visit quickanswerz.com for more math help/tutoring! Consider a rectangle with dimensions 7 inches by 10 inches. Let ABCD be the rectangle. We need to find the length of the diagonal. We know that the diagonals of a rectangle are same in length. So, it is enough to find the length of the diagonal BD. From the rectangle ABCD, it is clear that the triangle BCD is a right angled triangle. So, we can find the length of the diagonal using the Pythagorean Theorem. BD2 = BC2 + DC2 BD2 = 102 + 72 BD2 = 100 + 49 BD2 = 149 BD = &radic;149 BD = 12.207 So, the length of the diagonal is 12.21 inches. Source: www.icoachmath.com

### If you use the Pythagorean theorem to find the length of a diagonal in a square and all sides are 25m would the answer be 1250m?

Doesn't seem likely, does it? A diagonal 50 times the length of the sides? Diagonal = sqrt(252 + 252), ie sqrt 1250(!) which is 35.36 to the nearest hundredth.

### How do you find the diameter of a square?

Squares do not have diameters; circles have them. If you are referring to the diagonal of a square, then you would use Pythagorean's Theorem to determine the length of the diagonal. 'Square' the length of one side and multiply by 2, then take the square root of that number to get the length of the diagonal. that is = under root( 2 s) where s= side
