Density of solid copper is 8960 kg/metre cubed. Calculate the volume of 5000 kg of copper to two significant figures.

Explanation:

Density

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

Given the density of solid copper as , we will calculate the volume occupied by M=5000 Kg of copper solving the above equation for V:

Substituting:

Calculating:

Expressed to two significant figures:
