an auditorium measures 30.0 m ✕ 15.0 m ✕ 5.0 m. the density of air is 1.20 kg/m3. (a) what is the volume of the room in cubic fe et? 79458 correct: your answer is correct. ft3 (b) what is the weight of air in the room in pounds?
1 answer:
dimension = 30.0 m ✕ 15.0 m ✕ 5.0 m.
density = 1.20 kg/m3
(a)volume = lenght * breadth * height
= 30 * 15 * 5
= 2250 metre cube = 2.25 cubic meter
(b) mass of air = density * volume
mass of air = 1.2 * 2250
mass of air = 2700kg
weight = mass * 9.8
= 2700 * 9.8
= 26,460 N
The definition of Density is the amount of matter in a given space, or volume Density = mass/volume units for density kg/m^3 Density of water 1g/ml Salt water is denser that is why don't sink as easily. To know more about density visit : brainly.com/question/15164682
