Question

6. Calculate the mass of wooden block, which dimensions are 2.3 m ×1.5 m× 1.23 m. The density of wood is 900 kg/m?
​

Answer 1

Explanation:

density=mass/volume

so, mass = density * Volume

Answer 2

volume of wooden block = 2 × 0.25 × 0.1 m3 = 0.05 m3

 

Relative density of wood  = (density of wood )/ (density of water )

 

density of wood = 0.6 × 1000 = 600 kg/m3  

 

Mass of wood = 0.05 × 600 = 30 kg
