Question

Calculate the surface area-to-volume ratio of a cube whose sides are 3 cm long​

Answer 1

Answer:

2/cm

Step-by-step explanation:

The surface area formula for a cube of side s is A = 6s^2.  The volume formula is V = s^3.

Therefore, the surface area-to-volume ratio is

6s^2      6

------- = -------

 s^3       s

                                                             6          2

and if s = 3 cm, this ratio becomes --------- = ------

                                                            3 cm     cm
