Question

Density of solid copper is 8960 kg/metre cubed. Calculate the

volume of 5000 kg of copper to two significant figures.​

Answer 1

`V=0.56~m^3`

Step-by-step explanation:

Density

It's a measure of the mass of an object or substance per unit volume. It can be calculated as:

`\displaystyle D=(M)/(V)`

Given the density of solid copper as
`D=8960~Kg/m^3`, we will calculate the volume occupied by M=5000 Kg of copper solving the above equation for V:

`\displaystyle V=(M)/(D)`

Substituting:

`\displaystyle V=(5000)/(8960)`

Calculating:

`V=0.558~m^3`

Expressed to two significant figures:

`V=0.56~m^3`
