Answer 2

Given:

• Total surface area of cube = 384 cm²

Need to find:

• Volume of cube?

Solution:

We know that,

TSA of cube = 6a²

⇒ 6a² = 384

⇒ a² = 384/6

⇒ a² = 64

⇒ √a² = √64

⇒ a = 8 cm

∴ Side of cube is 8 cm.

━━━━━━━━━━━━━━━━━━━

Now, Finding Volume of cube,

Volume of cube = a³

⇒ (8)³

⇒ 512 cm³

∴ Hence, Volume of given cube is 512 cm³.
