Question

দুটি ঘনকের আয়তনের অনুপাত 1:8 হলে ঘনক দুটির সমগ্র তলের ক্ষেত্রফল অনুপাত কত?

Answer 1

Step-by-step explanation:

Given if the volume of two cubes are in the ratio 1:8 what is the ratio of total surface area of two cubes?

• Given volume of two cubes are in the ratio 1 : 8.
• So v1 / v2 = 1 / 8
• So a1^3 / a2^3 = 1 / 8
• Or a1 / a 2 = 1 / 2  
• Now ratio of their total surface area will be
• 6 a1^2 / 6 a2^2  
• = (a1 / a2)^2
•  = (1 / 2)^2  
• = 1 / 4

= 1 : 4
