Answer:
Surface area of cube is directly proportional to it's side , say 'a' in power 2 or a^2 and there are 6 surfaces totaling area of 6 a^2.
Volume of cube is directly proportional to cube of its side 'a' and is a^3.
As the ratio of surface area of the two cubes is 1:25 , ratio of their sides is √1:√25 or 1:5
So, ratio of their volumes is 1^3 : 5^3, or
1:125
I hope it's help you to understand:)))
if this is wrong answer so sorry
