Surface Area Argument

[CLAWS]

Possibly the most boringest thread I have ever created.

I am trying to explain "Surface area" to one of the folks at work.

Back when I was doing A-level biology, the lecturer drew two circles on the board. Sphere A was small and Sphere B was big. He then asked which one has the most surface area. Majority said Sphere B. But me, remembering the same question at GCSE level, said Sphere A.

He said I was correct and he explained it, but for the life of me I cannot remember the explanation. Can anyone help?

Ummmm..... huh?

Hmm interesting.

I remember reading in a biology text book something along the lines of -

"Animals use their teeth to grind food down into smaller particles, increasing the surface area available for digestion"

 

[CLAWS]

Maybe you're thinking surface area to volume ratios

Ah now that rings many bells. Quite possible this might be where I am getting mixed up.

Whats the difference here by the way? Bearing in mind I did A-level biology in 1995 and only got a C.

Good explanations by the way folks
