Answer:

[tex](\sqrt{30}-2\sqrt{5})\ m[/tex]

Step-by-step explanation:

we know that

The length of the side, s, of a cube with a surface area, SA is equal to the formula

[tex]s=\sqrt{\frac{SA}{6}}[/tex]

Step 1

Find the length of the side, s, of a cube with a surface area of [tex]180\ m^{2}[/tex]

we have

[tex]SA=180\ m^{2}[/tex]

substitute in the formula

[tex]s=\sqrt{\frac{180}{6}}[/tex]

[tex]s=\sqrt{30}\ m[/tex]

Step 2

Find the length of the side, s, of a cube with a surface area of [tex]120\ m^{2}[/tex]

we have

[tex]SA=120\ m^{2}[/tex]

substitute in the formula

[tex]s=\sqrt{\frac{120}{6}}[/tex]

[tex]s=\sqrt{20}=2\sqrt{5}\ m[/tex]

Step 3

Find the difference of the length sides

[tex](\sqrt{30}-2\sqrt{5})\ m[/tex]
