Question

how many cubes are possible with a total surface area of 486cm square

Answer 1

Answer:

first of all find its cube after that you will find that your answer

Answer 2

Answer:

Let side length of the cube = a cm

We know that

***********************************************

Total surface area of the cube = 6a ^2

**********************************************

Given

Total surface area of the cube = 486

Square cm

6a ^2 = 486

a^2 = 486/6

After cancellation

a^2 = 81

a = + or - sqrt(81)

a = 9 or -9

But side length should not negative.

Therefore

Side length of the cube = a = 9cm

I hope this will usful you.
