QUESTION⬇️⬇️

find the total surface area of a cube whose volume 343 cm²

ANSWER⬇️⬇️⬇️

Volume of a cube = 343cm²

Formula of Volume of cube= a³

a³ = 343cm²

$\sqrt[3]{343} = 7$

SO, SIDE OF A CUBE IS 7 cm

Now, we will Find TSA of a cube

FORMULA OF TSA OF A CUBE= 6a²

6a² = 6(7)² = 6(49) = 294

SO, TSA OF A CUBE IS 294 cm²

Answer 2

Step-by-step explanation:

Volume of cube = 343 cm³

Side of cube, a = 3√(343) = 7m

We know that,

Surface area of cube = 6 × side²

= 6 × 7²

= 6 × 49 = 294cm²
