Question

A block of aluminum has a mass of 39.589 g and measures 5.10 cm by 2.50 cm by 1.15 cm. what is the density of the rectangular aluminum block?

Answer 1

In order to calculate the density of the block, we must calculate its volume first.

The volume of the block is given by:

$V=5.10 cm \cdot 2.50 cm \cdot 1.15 cm =14.66 cm^3$

So now we can calculate the density of the block as the ratio between its mass and its volume:

$d=\frac{m}{V}=\frac{39.589 g}{14.66cm^3}=2.7 g/cm^3$
