Step-by-step explanation:
The diagonal of a cube is nearly as simple as the Pythagorean theorem.
It is very simple:
(length)2 + (width)2 + (height)2 = (diagonal)2
In other words, you simply take the square root of the sum of the squares of the length, width, and height of the cube.
Since the length, width, and height of a cube are equal, you can simply multiply one side squared by 3, like this:
For example:
√ 3(x2) = d
