The dimensions of wooden black are `2 m xx 0.125m xx 0.10m`. If the relative density of wood is 0.6, calculate the mass of wooden block Density of water is `10^(3)kgm^(-3)`.

Answer

The mass of the wooden block is 30kg.

Explanation

Density of wood
=relative density `xx` density of water
`=0.6 xx 10^(3)=600kgm^(-3)`
Volume of the wooden block
`=2 m xx 0.25 m xx 0.10m =0.05m^(3)`
Density `=("Mass")/("Volume")`
`=600kgm^(-3) xx 0.05 m^(3)=30kg`
