13.33 cm

Step-by-step explanation:

Given, ratio of volumes v ÷ V = 8 ÷ 27

This ratio is applicable to heights of same containers, as the volume is directly proportional with height (V=Ah, A- base, h- height)

So we have:

h ÷ H = 8 ÷ 27

and

H=45 cm

Then,

h ÷ 45 = 8 ÷ 27h = 45 × 8/27h = 40/3 = 13.33 cm
