Surface area to volume ratio..?

Hello friends....i have two doubts on SA/V ratio

 

1) Whether the S.A/V ratio depends only on size & shape.....or else on its orientation or inclined position also?

2)Whether the S.A/V ratio is same for both cube and sphere?

  • Hi mam....

         i have gone through the equations 6.3, 6.4, and 6.5 and also figure 6.18.....

    I have a small doubt ..with what respective they have drawn the graph.....like for Sphere and Cylinder the expressions are in radius R and for cube it is side length L....so is it necessary to make relation between them while comparing all three right.....

    so do we need to make volume constant or size constant in the case

  • Thank you for replying me....But while we calculating mathematically, do we need to calculate by keeping constant volume or constant size.....

  • SA/V of cube=6/a..:a is the side of cube

    and sphere is 3/r...where r is the radius of sphere....

    But if we think logically we can write "a=2r" as sphere fits into cube and then calculate both are same...

    YesS.A./V ratio only depends on the size and shape so the S.A./V ratio for sphere and cube is different.
