how will you determine the density of a cuboidal solid

Solution,
1. The volume (V) of the cuboidal solid is first determined either by measuring its dimensions or by collecting the displaced water in a measuring cylinder upon dipping the solid into the water.
2. Finding the mass (m) of the solid.
3. The density (d) of the solid is determined using the following formula:
$d=\frac{m}{V}$
