Answer 2

Answer:

The area to be painted is 486 cm².

Step-by-step explanation:

Metal cube has a volume of 27 cm³

So,

We know volume of cube = (side)³

$\sf{Side \: of \: cube = \sqrt[3]{27}} </p><p>$

Side of cube = 9

Cube has 6 faces

So,

TSA of cube = 6 × side²

⇒ 6 × 9²

⇒ 6 × 81

⇒ 486

TSA of cube = 486 cm²

Therefore, the area to be painted is 486 cm².
