Question

The volume of cube is 1728m cube.Find it's surface area

Answer 1

Answer:

Volume of cube = a³

⇒ a³ = 1728 m³

⇒ a = ∛ 1728

⇒ a = 12 m

Surface Area of Cube :

⇒ LSA = 4a²

⇒ LSA = 4 ( 12 )²

⇒ LSA = 4 ( 144 )

⇒ LSA = 576 m²

⇒ TSA = 6a²

⇒ TSA = 6 ( 12 )²

⇒ TSA = 6 ( 144 )

⇒ TSA = 864 m²

This is the required answer.
