Question

The surface area of a cube whose edge equals to 3cm is:

Answer 1

Answer:

TSA =

$6 {a}^{2}$

TSA =

$6 {3}^{2}$

TSA =

$6 \times 9$

TSA = 54

$cm^{2}$

Answer 2

The surface area of a cube with side 3 cm is 54 square centimeters.

Given:

Side of the cube = 3 cm

To find:

The surface area of the sphere

Calculation:

We know that cube is a 3 dimensional structure which has 6 faces and each face is in the form of square.

The surface area of any three dimensional structure is the total area of all the surface that encompasses the object.

Length of a side = 3 cm

Area of the side = 3 × 3 = 9 square centimeters.

Now a cube has 6 sides.

Hence total surface area = 9 × 6 = 54 square centimeters

Therefore the surface area of the cube is 54 square centimeters .
