total surface area of cube = 6 square
726 = 6 a square
726/6 = a sq
121 = a square
11 = a
side of cube = 11 cm. hope it helps :)

hiii!!!
here's ur answer...
let the side (edge) of the cube be a.
TSA (total surface area) of the cube = 726cm²
therefore 6a² = 726cm²
==> a² = 726/6
==> a² = 121
==> a = √121
==> a = 11cm
VERIFICATION :-
TSA of the cube = 6a²
= 6 × 11²
= 6 × 121
= 726cm²
hence verified
thus the edge of the cube is 11cm
hope this helps..!!
