Answer:
A 0.4 g/cm³
Explanation:
The density of a substance, which is a cube in this case, can be calculated by using the formula:
Density = mass/volume
Where;
Density = g/cm³
Mass = grams
Volume = cm³
In this question, each side of the cube measures 3 cm. This means that the volume of the cube can be got by multiplying 3 × 3 × 3 = 27cm³. Hence, volume of the cube = 27cm³.
Mass of the cube = 12g
Density = 12/27
Density = 0.4444
Approximately, density = 0.4 g/cm³
