Answer:

[tex]V = \frac{2}{3} cm^2[/tex]

Step-by-step explanation:

Given

[tex]V = 6s^2[/tex]

Required

Find the surface area when the length is [tex]\frac{1}{3}\ cm[/tex]

To do this, we simply substitute [tex]\frac{1}{3}\ cm[/tex] for s in the given formula

[tex]V = 6s^2[/tex] becomes

[tex]V = 6 * \frac{1}{3}^2[/tex]

[tex]V = 6 * \frac{1}{3} * \frac{1}{3}[/tex]

Combine Fractions

[tex]V = \frac{6 * 1 * 1}{3 * 3}[/tex]

[tex]V = \frac{6}{9}[/tex]

Simplify Fraction

[tex]V = \frac{2}{3} cm^2[/tex]
