Answer:
4:9
Step-by-step explanation:
Let the Sides of cube be a,b
Volume of cubes are given by a^3, b^3
Ratio of volumes is given by a^3 : b^3 = 8:27
=> (a/b)^3 = (2/3)^3
=> (a/b) = (2/3)
=> a = (2/3)b
The surface area of Cubes is given by 6a², 6b²
=> 6a² : 6b²
=> a² : b²
put a = (2/3)b
=> (2/3 b)² : b²
=> 4/9 : 1
=> 4:9
