Heya,

Given:-
TSA of cube = 726cm^2

To find:-
Length of the cube

Solution:-

TSA = 6a^2
726 = 6a^2
726/6 = a^2
121 = a^2
√121 = a
√11×√11 = a
11 = a

Therefore,
The length of the cube is 11cm

Hope my answer helps you :)

Regards,
Shobana

 T.S.A. OF CUBE = 726 sq. cm 
6a² = 726
a² = 726/6 = 121
a = √121
a = 11cm

SO, LENGTH OF EDGE = 11cm.
