if a wooden beam is 30 x 20 x 500 cm. and has a mass of 150 kg. what is the density of the wood
density= mass/volume=150kg/(30*20*500) in kg/cm^3
To find the density of the wood, you need to divide its mass by its volume. The given dimensions of the wooden beam are 30 cm (length) x 20 cm (width) x 500 cm (height).
1. Calculate the volume of the wooden beam:
Volume = length x width x height
Volume = 30 cm x 20 cm x 500 cm
Volume = 30000 cm³
2. Convert the volume from cm³ to m³:
1 m³ = 1000000 cm³
Volume (m³) = Volume (cm³) / 1000000
Volume (m³) = 30000 cm³ / 1000000
Volume (m³) = 0.03 m³
3. Divide the mass of the wooden beam (in kg) by its volume (in m³):
Density = mass / volume
Density = 150 kg / 0.03 m³
4. Calculate the density:
Density = 5000 kg/m³
Therefore, the density of the wood is 5000 kg/m³.
