Question

9. The area of one face of a cube is 24 cm What is the total surface area of
the cube?​

Answer 1

Step-by-step explanation:

That is, each side of the cube is 6 cm. Now, we will find the area of one face of the cube. Multiply the area of one face of the cube by 6 to find the total area of 6 faces. Hence, the total area of the 6 faces in cm2 is 216 cm2.

Answer 2

Answer:

The perimeter of one face of a cube is 24 cm. Find the total area of the 6 faces in cm

2

Answer

Correct option is

A

216

Each face of a cube is a square.

Let the side of the square face =a cm

Perimeter of the square =4a=24 cm =>a=6 cm

Total surface area of a cube of edge a =6a

2

So, the total surface area of the cube of edge a =6 cm is =6(6)

2

=216cm
