A wooden block of dimensions 10cmxx20cmx...

A wooden block of dimensions `10cmxx20cmxx50cm` weighs 6-5 kg Calculate the density of the block.

Text Solution

Verified by Experts

Here, volume of the block, `V=10cmxx20cmxx50cm=10000cm^3`
`=10000xx10^-6cm^3=10^-2m^3`
mass of the block, `M=6.5kg`
Density of the block, `d=(M)/(V)=(6.5kg)/(10^-2)=650(kg)/(m^3)`
