Question

find the surface area of a cube of side length 5cm

Answer 1

Answer:

150 cm sq

Step-by-step explanation:

Side of a cube = 5cm

Surface area of cube = 6 L square

= 6 ×(5×5)cm sq

= 6 ×25 cm sq

= 150 cm sq

Answer 2

Answer:

The total surface area of a cube is $150cm^{2}$

Step-by-step explanation:

As per the data given in the above question,

Given that the side of a cube is 5 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,

$A=6\times 5^{2} \\A=6\times 5\times 5\\A=6\times 25\\A=150$

The total surface area of a cube is $150cm^{2}$
