Living room

How many people can live in a room with dimensions: a = 4m b = 5m c = 2.5m if one person needs 15m cubic space (i. E. Air . .. )?

Correct answer:

n =  3

Step-by-step explanation:

$$\begin{gathered} a=4\text{ m } \\ b=5\text{ m } \\ c=2.5\text{ m } \\ V=a\cdot b\cdot c=4\cdot 5\cdot 2.5=50{\text{m}}^3 \\ {V}_1=15{\text{m}}^3 \\ n=\lfloor V\mathrm{/}{V}_1\rfloor =\lfloor 50\mathrm{/}15\rfloor =3 \end{gathered}$$
