Question

What is the Diagonal of the cube​

Answer 1

${\bold{\huge{\fbox{\color{Maroon}{ANSWER}}}}}$

A diagonal of a cube is a segment joining two points that are not the endpoints of an edge. Whereas both diagonals of a square have the same length, a cube has diagonals of two different lengths, the shorter ones lying on square faces and the longer ones passing through the center.

Answer 2

Answer:

A diagonal of a cube is a segment joining two points that are not the endpoints of an edge. Whereas both diagonals of a square have the same length, a cube has diagonals of two different lengths, the shorter ones lying on square faces and the longer ones passing through the center.

The main diagonal of any cube can be found by multiplying the length of one side by the square root of 3.
