Answer: [tex]864\text{ mm}^2[/tex]
Step-by-step explanation:
Given: the side length of the cube = 12mm
The surface area of the cube is given by :-
[tex]\text{Surface area }=6(side)^2[/tex]
Therefore, the surface area of the given cube will be :-
[tex]\text{Surface area }=6(12)^2=6\times144=864\text{ mm}^2[/tex]
hence, the surface rae of the cube is [tex]864\text{ mm}^2[/tex]
