Lateral Edge of the Parallelepiped

The online calculator provides the opportunity to quickly and accurately calculate the length of the lateral edge of the given parallelepiped, knowing its edge lengths and diagonal length.

If the lengths of two parallelepiped edges are known a and c and its diagonal d, you can calculate the length of the lateral edge b using the Pythagorean theorem.

Since the parallelepiped is rectangular, its diagonal d is the hypotenuse of the right triangle, and the lengths of the two known edges a and c are the legs of this triangle.
Thus, the formula for calculating the length of the lateral edge b will be: √(d² - a² - b²)
