Answer:
The mass is 4kg
Step-by-step explanation:
Density of an object is defined as the ratio of the mass of the object to its volume. Mathematically,
Density = mass/volume
Mass is measured in kilogram (kg)
Volume is measured in m³
From the formula;
Mass = Density × volume
Mass = 2kg/m³ × 2m³
Mass = 4kg
