Question

the ratio of the volumes of two cubes is 8is to27. find the ratio of their surface areas​

Answer 1

Answer:

A1/A2=(8/27)^1/3

A1/A2=2/3

Step-by-step explanation:

ratio of surface areas is (A1/A2)^2=(2/3)^2

=4/9

Answer 2

Answer: 4 : 9

Step-by-step explanation:  

let one cube has side s1 and other has side s2, therefore,

ratio of volumes = s1^3 / s2^3  = 8/27 (GIVEN)

Therefore, s1 / s2 = 2/3

Now, ratio of surface areas = 6(s1)^2 / 6(s2)^2

                                             = (s1)^2 / (s2)^2

                                             = 4/9

THEREFORE ANSWER IS 4 : 9.
