Hello Friend !
The answer is given below :
Given, total surface area of a cube = 726 m²
We know, total surface area of a cube is 6a² , where 'a' is the side of cube.
Therefore, 6a² = 726
⇒ a² = 121
⇒ a = 11
Therefore side of a cube is 11 m
Hope this helps !!!

TSA of cube =6*side^2=726m^2
=>side^2=726/6 = 121
=> side=√121
=> side= 11m
Hence, side of the cube is 11 meter.
