Given
Relationship between sides and surface areas
Find
Conclusion from the table
Explanation
From the table we can see that sides double in 1st, 2nd and 4th case
So comparing them
When side =1 then Surface area = 6 cm sq
When side = 2 then Surface area = 24 cm sq
Here we can see that when the side doubles, the surface area quadruples
Similar result is obtained when in relation of side = 2 and side 4
Final Answer
When the side doubles, the surface area quadruples
option (a) is correct
