So ratio of their sides is 4:5 ok bro
hercules3:
how u can tell me in detail
The T.S.A of cube is 6side^2
so 6 upon 6 is cancelled
so it is given that the ratio of square two side is 16:25
If we consider the side then it is 4:5

Let the one side of a face of 1st cube =y
And 2nd cube=z
Then surface area of 1st cube=6y^2
And 2nd cube =6z^2
Given,surface area of 1st cube/2nd cube=16/25=6y^2/6z^2=y^2/z^2
So,y/z=√16/25=4/5
So,the ans is 4:5
And 2nd cube=z
Then surface area of 1st cube=6y^2
And 2nd cube =6z^2
Given,surface area of 1st cube/2nd cube=16/25=6y^2/6z^2=y^2/z^2
So,y/z=√16/25=4/5
So,the ans is 4:5
