What is the approximate mass of air in a living room 6.0 m times 3.9 m times 2.7 m?
Volume, V, in m³= width*length*height (all in metres)
Air density, ρ = 1.293 kg/m³
So approximate total mass
ρ*V kg.
81.7kg
To find the approximate mass of air in a living room, you need to calculate the volume of the room and then multiply it by the density of air.
Step 1: Calculate the volume of the living room.
The volume (V) of a rectangular room can be determined by multiplying its length (L), width (W), and height (H) together. In this case, the length is 6.0 m, the width is 3.9 m, and the height is 2.7 m.
V = L × W × H
V = 6.0 m × 3.9 m × 2.7 m
Step 2: Multiply the volume by the density of air.
The density of air is typically around 1.2 kg/m³.
Mass of air = V × density of air
Mass of air = (6.0 m × 3.9 m × 2.7 m) × 1.2 kg/m³
Now, you can calculate the approximate mass of air in the living room.
