Question

A piece of wood that measures 2.7 cm x 5.5 cm x 3.9 cm has a mass of 84 g what is the density of the wood

Answer 1

The density of the wood : 1.45 g/cm³

Further explanation

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

`\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}`

ρ = density

m = mass

v = volume

• Volume of the wood

`\tt V=2.7* 5.5* 3.9=57.915~cm^3`

• density

`\tt \rho=(m)/(V)\\\\\rho=(84~g)/(57.915~cm^3)=\boxed{\bold{1.45`g/cm^3}}`
