Question

If the ratio of the volume of two cubes is 27:125, the ratio of their surface areas is _______.

Answer 1

Answer:

Answer is 9:25

Step-by-step explanation:

let 'a' be the side of the first cube and 'b' be the side of the second one

a^{3} / b^{3}a3/b3 =27/125

a/b=∛27/∛125

a/b=3/5

the ratios of their surface areas =6a^{2}/6b^{2}6a2/6b2

=6*3*3/6*5*5

=9:25

Ans.. therefore the ratio of their surface areas = 9:25
