Explanation:
Volume (V) = 100 cm³
Mass (M) = 159 g
Density (D) =?
We know density is defined as mass per unit volume so
D = m / v
= 159 / 100
= 1.59 g /cm³
The density of the metal block is 1.59 g/cm³.
Note : If the question is asked to change the units in SI system then u have to write in kg/m³.
Hope it will help :)❤
