the dimensions of block are 2m0.25m0.10m.of relative density of wood is 0.6,calculate mass of the block in kg .Density of water=10^3 kg m^-3

Open in App

Solution

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
