1.	. Two Cubes have their volumes in the ratio 1: 27. Find the ratio of their surface areas.
Answer» Let their edges be a and b.Then,a³/b³ = 1/27⇒ (a/b)³ = (1/3)³⇒ a/b = 1/3 --------------------(1)Therefore, Ratio of the surface area,⇒6a²/6b²⇒ a²/b²⇒ (a/b)²⇒(1/3)² [From (1)]⇒1/9⇒i.e. 1 : 9Ratio of the surface area= 1 : 9 hit like if you find it useful
