Answer:
The answer to your question is 8/3 u²
Step-by-step explanation:
Data
length of the side = 2/3
Surface area = ?
Process
1.- Calculate the area of one face
Area = side x side
-Substitution
Area = 2/3 x 2/3
-Result
Area = 4/9
2.- Calculate the area of the cube (a cube has 6 faces)
Surface area = 4/9 x 6
= 24/9
-Simplification
Surface area = 8/3 u²
