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 . .. )?

Result

n =  3

Solution:

a=4 m b=5 m c=2.5 m  V=a⋅ b⋅ c=4⋅ 5⋅ 2.5=50 m3 V1=15 m3 n=⌊V/V1⌋=⌊50/15⌋=3a=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 / V_{1} \rfloor=\lfloor 50 / 15 \rfloor=3
