How do you calculate the ratio of surface area to volume if numerator is cm2, and denominator is cm3? ?

Question

My surface area is 36.0

My volume is 14.8

Answer 1

36cm^2/14.8cm^3=2.43/cm

ANSWER

Answer 2

you get a ratio with a dimension of 1/cm

SA/V=36 cm^2/14.8cm^3=2.43/cm

Answer 3

You cannot do ratios when the units are different! - you can however do a 'rate" (something per something else)

SA / Vol = 36cm² / 14.8cm³

= 2.43 cm² / cm³ (2dp)

that is: 2.43cm² of surface area per 1 cm³ volume

I dont think it makes sense to divide the units
