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.
