What is an object that has a low surface area to volume ratio, and explain why it has such a ratio?

Question

I'm having a hard time trying to think of an example other than a sphere. 

 

I am also wondering what could be another object that has a high surface area to volume ratio, and why it has such a ratio?

Hi Mickayla,

A sphere or a cube works although the size of the object is what will give you low SA:V

 

Sphere example:

 

SA = 4(pi)r²

V = (4/3)(pi)r³

 

A very small sphere, say r = 1 

 

SA = 4(pi)

V = (4/3)(pi)

 

giving a high SA:V because SA > V

 

When the sphere is large, say r = 10

 

SA = 400(pi)

V = (4000/3)(pi)

 

SA:V is low because SA < V
