Question

dimensions of a wooden block at 2 m × 0.25 m × 0.10 m. If the relative density of wood is 0.6 calculate the mass of a block in kg.

Answer 1

Relative Density is Density of substance / Density of water

0.6 = Density of substance / 1000

= 600 = Density of substance

Density = mass / volume

600 kg / m3 = Mass / (2 * 0.10 * 0.25) m3

600 kg / m3= Mass / 0.05 m3

600 * 0.05 = Mass

30 kg

Ans: 30 kg
