Answer:

s = √(30) - 2√(5) m

Explanation:

Given:

Formula for side length of cube,
$s = \sqrt{(SA)/(6)$

Where, S.A = surface area of a cube, and s = side length.

Required:

Difference in side length between a cube with S.A of 180 m² and a cube with S.A of 120 m²

Solution:

Difference = (side length of cube with 180 m² S.A) - (side length of cube with 120 m² S.A)

$s = (\sqrt{(180)/(6)}) - (\sqrt{(120)/(6)})$

s = (√(30)) - (√(20))

s = √(30) - √(4*5)

s = √(30) - 2√(5) m
