Question

Two cubes have their volumes in the ratio 8:27. The ratio of their curved surface areas is:​

Answer 1

Answer:

4 : 9

Step-by-step explanation:

Ratio of volumes = 8 : 27

8 = 2×2×2 or 2³

27 = 3×3×3 or 3³

Ratio of sides = 2 : 3

Curved Surface Area of cube = 4 × (side)²

Ratio of C.S.A. = 4×(2)² : 4×(3)² = 4 : 9
