Answer:
see explanation
Step-by-step explanation:
A cube has 6 congruent square faces
The area of 1 face = [tex]\frac{2}{3}[/tex] × [tex]\frac{2}{3}[/tex] = [tex]\frac{4}{9}[/tex]
Multiply by 6 to obtain surface area of cube
surface area = 6 × [tex]\frac{4}{9}[/tex] = [tex]\frac{24}{9}[/tex] = [tex]\frac{8}{3}[/tex] units²
