Answer: \(61.44\ m^2\)
Step-by-step explanation:
It is given that the side length of cube = 3.2 m
The surface area of a cube is given by :-
\(\text{Area of cube}=6(side)^2\)
Therefore, area of the given cube will be :_
\(\text{Area of cube}=6(3.2)^2\\\\\Rightarrow\ \text{Area of cube}=6(10.24)\\\\\Rightarrow\ \text{Area of cube}=61.44\ m^2\)
Hence, the surface area of the cube = \(61.44\ m^2\)
