Question

Find the length of a cube whose total surface
is 162 cm^2​

Answer 1

Answer:

Here, The length of a side of the given cube is 3(root3)cm.

Step-by-step explanation:

Here, As per our given question,

TSA of the Cube=162cm^2

So, its length =?

As we know that formula for TSA of a cube:

=TSA=6(side)^2 (Side is also considered as a)

=162=6a^2

=a^2=162/6

=a^2=27

By doing square root on both sides, we get,

=a=3(root3)

Hence, The length of a side of the given cube =3(root3)cm.

Thank you.
