Determine the mass of air in a classroom with dimensions of 5x12x3 m at t = 25.

Determine the mass of air in a classroom with dimensions of 5x12x3 m at t = 25. Take the air density equal to 1.29kg / m ^ 3

Let’s calculate the volume of the classroom, multiplying, respectively, its length, width and height – 5 m * 12 m * 3 m = 180 m³.

Now we will find the required air mass based on the formula ρ = m / V, where ρ is the density of the substance, m is its mass, V is the volume it occupies. Hence m = ρV. m = 1.29 kg / m³ * 180 m³ – m = 232.2 kg.

Answer: The mass of air in the classroom will be 232.2 kilograms.
