$s=\sqrt{30}-2\sqrt{5}$ mtrs.

step-by-step explanation:

first sa=180 square meters

as it is given that $s=\sqrt{\frac{sa}{6}}$

putting the value of sa

$s=\sqrt{\frac{180}{6}}$

$s=\sqrt{30}$ mtrs.

now, when sa = 120 sq mtrs. using the formula we get

$s=\sqrt{\frac{sa}{6}}$

$s=\sqrt{\frac{120}{6}}$

$s=\sqrt{20}$

$s=\sqrt{2\times2\times5}$

$s=2\sqrt{5}$ mtrs.

the side of cube with surface area 180 sq mtrs. is longer by side of cube with surface area 12 sq. mtrs. by

$s=\sqrt{30}-2\sqrt{5}$ mtrs..
