Question

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

Answer 1

2/cm

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
