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

Sandeep,

Refer to Chapters 6.1 and 6.2 of the publication above (beginning on page 177; specifically figure 6.18, .19, .. and equations on page 186) for given nanostructure formulae of various nanomaterial classes (discrete, surface, bulk), shape:size effects, their dimensionality, radii of spheres, cylinders, etc..., surface curvature, strain confinement, and quantum effects. Click on title line; I have supplied the link.

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...

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

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
