TSA = 726
6a² = 726
a² = 726/6 = 121
a = √121 = 11cm
6a² = 726
a² = 726/6 = 121
a = √121 = 11cm

Answer :
The length of its edge is 11 cm.
Step-by-step explanation :
Total surface area of cube = 6 ( side )²
∴ 6 ( side )² = 726
⇒ ( side )² = 726 / 6
⇒ ( side )² = 121
⇒ side = √ 121
⇒ side = 11 cm
Hence, the length of the cube is 11 cm.
The length of its edge is 11 cm.
