Question

find the total surface area of a cube whose volume is 343cm square

Answer 1

Heya friend,

Let the side of a cube be x cm. Then,

Volume of a cube = side × side × side

343 = x × x × x

=> 343 = x^3

=> x = 3√343

=> x = 7

Hence, the side of a cube is 7 cm.

Total surface area of a cube = 6 × (length)^2

= 6 × (7)^2

= 6 × 49

= 294 cm^2





Thanks

Answer 2

hello..



Here's the answer you are looking for

Let the side of the cube be a

Volume = a³ = 343

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

So side of the cube is 7cm.

Total surface area = 6a² = 6(7)² = 6(49) = 294cm²
