Question

calculate the mass of air in a room if the floor dimensions are 10m × 12m and height is 400 cm the density of air is 1 .26 kg/M³ 3​

Answer 1

Explanation:

first find the volume of room --->

$v \: = 10 \times 12 \times (400 \times {10}^{ - 2} ) \times = 480 \: {m}^{3}$

then find the mass

$mass \: = \: density \: \times \: volume \: = 480 \times 1.26 = 604.8 \: kg$
