Question

calculate the mass of air in a cubical container of side 5 m. density of air is 1.3 kg/m³.

please help me friends​

Answer 1

Answer:

Step-by-step explanation:

mass=density x volume =1.3 x 5 =6.5kg

hope this helps

Answer 2

Step-by-step explanation:

side of cubial container (a) =5m

therefore, its volume=a³=5×5×5=125m²

density of air=1.3 kg/m³

also, we know that. density = mass/volume

1.3 = mass × 125

mass = 125/1.3= 96.15 kg
