Answer 1

Answer:

the total surface area of a cube whose volume is 343cm³ = 1029

Answer 2

Given:-

• Volume of a cube is 343 cm³.

⠀

To find:-

• Total surface area of a cube.

⠀

Solution:-

According to the question,

⠀

Firstly,

⇢ Volume = 343 cm³

⇢ Volume = a³ = 343

⇢ Volume = 7 cm

⠀

Now,

⇢ TSA = 6a²

⇢ TSA = 6 × 7²

⇢ TSA = 6 × 7 × 7

⇢ TSA = 6 × 49

⇢ TSA = 294

⠀

Hence,

• The total surface area of a cube is 294 cm².
