Question

What is the surface area of a cube with a volume of 343cm2?

Answer 1

Answer:

Surface Area of Cube=294 cm²

Step-by-step explanation:

Given:-

Volume of the cube=343 cm².

To Find:-

The Surface Area of the Cube.

Formula Applied:-

Volume of Cube=(side) ³

Volume of Cube=(side) ³Surface Area of Cube=6(side) ²

Solution:-

Let the side of Cube be a cm.

Volume of Cube=(a)³

343=(a)³

$a = \sqrt{343} cm^{3}$

a=7 cm

Surface Area of Cube=6×(a)²

Surface Area of Cube=6×(7)²

Surface Area of Cube=6×49

Surface Area of Cube=294 cm²

Answer 2

Answer:

294cm2

Step-by-step explanation:

Volume of Cube=(a)³

343=(a)³

a=7 cm

Surface Area of Cube = 6×(a)²

Surface Area of Cube = 6×(7)²

Surface Area of Cube = 6×49

Surface Area of Cube = 294 cm²
