calculate the mass of air in a room measuring 5m*8m*10m if the density of air is 1.3kg/m cube

V = 5 * 8 * 10 = 400 m^3.

Mass = 400m^3 * 1.3kg/m^3 = 520 kg.

To calculate the mass of air in the room, you need to multiply the volume of the room by the density of air.

Step 1: Calculate the volume of the room.
Given dimensions:
Length = 5m
Width = 8m
Height = 10m

The formula to calculate volume is:
Volume = Length x Width x Height

Volume = 5m x 8m x 10m
Volume = 400m³

Step 2: Multiply the volume by the density.
Given density:
Density of air = 1.3 kg/m³

Mass = Volume x Density
Mass = 400m³ x 1.3kg/m³
Mass = 520kg

Therefore, the mass of air in the room is 520 kilograms.

To calculate the mass of air in the room, we need to find the volume of the room and multiply it by the density of air.

Step 1: Calculate the volume of the room.
The volume of a rectangular room can be found by multiplying its length, width, and height.
Given:
Length = 5m
Width = 8m
Height = 10m

Volume = Length × Width × Height
Volume = 5m × 8m × 10m
Volume = 400 cubic meters (m³)

Step 2: Multiply the volume by the density of air.
Given:
Density of air = 1.3 kg/m³
Volume of the room = 400 m³

Mass of air = Volume × Density
= 400 m³ × 1.3 kg/m³

Mass of air = 520 kg

Therefore, the mass of air in the room measuring 5m × 8m × 10m, with a density of 1.3 kg/m³, is 520 kg.
