Answer: LAST OPTION
Step-by-step explanation:
To solve this problem you must:
- Calculate the surface area of one of the squares, with the formula for calculate the surface area of a square, where "s" is the lenght of any side of the square, then you obtain;
[tex]A=s^{2}=(4mm)^{2}=16mm^{2}[/tex]
- Now, you must multiply this area by 6 (6 faces of the cube), then the results is:
[tex]SA=16mm^{2}*6=96mm^{2}[/tex]
