Two cubes have their volumes in ratio of 1:27. What is it's surface area |
|
Answer» are in the ratio 1: 27 Let the sides of the cubes are a, b.then1/27 = 1/3 = a³/b³b/a = 3Since we KNOW that the surface areaof a CUBE is 6a²i. e the surface area will beproportional to the square of sides.Therefore on squaring = a²/b² = 1²/3²= ⅑ = 1 : 9 |
