Answer:
Surface area of cube=6a^2
According to the given condition,
6a^2=726.
Implies, a^2=121.
Implies, a=11.
Volume of the cube=a^3=11^3=1331 cubic cm.
Step-by-step explanation:
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
Now,
Volume of cube = ( side )³
⇒ Volume = ( 11 × 11 × 11 ) cm³
⇒ Volume = 1331 cm³
