Answer 2

Answer :

The side of the cube is 20.68 m, whose surface area of a cube is 2568 m²

Step-by-step explanation :

To Find,

• The side of the cube ...... ( ? )

Given that,

• The surface area of a cube is 2568m²

Solution,

Let the side of the cube be " a " m.

Then, the total surface area of the cube = 6a² m²

∴ 6a² = 2568

➫ a² = 2568 / 6

➫ a² = 428

➫ a² = √ 428

➫ a² = 20.68 ≈

∴ Hence, the side of the cube is 20.68m ≈
