Q. The ratio of the total surface areas of two similar cuboids is 25 : 49. The ratio of their volumes is:
✅ Correct Answer: (B)
125 : 343
Explanation: Surface area ratio = k². Hence k = 5 : 7. Volume ratio = k³ = 125 : 343.
Explanation by: Mahesh Chandra
Surface area ratio = k². Hence k = 5 : 7. Volume ratio = k³ = 125 : 343.
