Question

If the body diagonal of a cube crystal is 2.50 angstrom,the approximate value of edge length is?

Answer 1

Do it by yourself

Be self independent

Answer 2

The edge length of the cube crystal is 1.44 angstrom.

Given:

The body diagonal of a cube crystal is 2.5 Angstrom.

To Find:

The approximate value of the edge length

Solution:

Let the side length of the cube be given as a.

Therefore, the body diagonal of the cube is given by $\sqrt{3} a$.

Hence using the given value, we can calculate a.

$\sqrt{3}a =2.5\\\\ a=\frac{2.5}{\sqrt{3} } \\\\a=1.44$

The edge length is 1.44 angstrom.
