Answer:
The surface area of the fish tank is 864 in².
Step-by-step explanation:
The surface area of cube is
\(A=6a^2\)
Where, a is side length.
It is given that cube tank has a side length of 12 inches. It means a=12.
The area of fish tank is
\(A=6(12)^2\)
\(A=864\)
Therefore the surface area of the fish tank is 864 in².
