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 :)

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