Question

the side of a cube is 2cm,find its total surface area

Answer 1

We know that, TSA of Cube = 6 *(side)^2
                                             = 6*2*2
                                             = 24 cm^2

Answer 2

Answer:

The total surface area of a cube is $24cm^{2}$

Step-by-step explanation:

As per the data given in the above question,

Given that the side of a cube is 2 cm,

We have to find the total surface area of a cube,

Here we have to use the formula of the cube,

$A=6\times a^{2}$

Where a is the side of the cube,

Substitute the value of side in the above area formula we get,

$A=6\times a^{2}$

Squaring a number is to multiplying a number by itself,

$A=6\times 2^{2} \\A=6\times 2\times 2\\A=6\times 4\\A=24$

The total surface area of a cube is $24cm^{2}$
