Step 1
Given Similarity ratio=47
Similarity ratio : if two solids are similar then. their corresponding sides are all proportional.
Step 2
Ratio of surface areas=(similarity ratio)2
Surface area is two dimensional property.
Ratio of surface areas=(similarity ratio)2
=(47)2=1649
Ratio of surface areas=1649
