In this issue, we understand the area, as well as we require to identify the size of among the sides of the dodecahedron. Consequently, we make use of the area formula as well as address for a:

$$ A _ {s} =3sqrt {25 +10 sqrt {5}} ~ {{} ^ 2} $$

$ latex A _ {s} =20.65 ~ {{} ^ 2} $

$ latex 120= 20.65 ~ {{} ^ 2} $

$ latex 5.81= a ^ 2$

$ latex a= 2.41$

The dodecahedron has sides with a size of 2.41 in.
