The volume \( V \) of a cube is calculated using the formula:
\[ V = s^3 \]
where \( s \) is the length of a side of the cube. For a cube with a side length of 1.5 cm, the calculation is:
\[ V = (1.5 , \text{cm})^3 = 1.5 , \text{cm} \times 1.5 , \text{cm} \times 1.5 , \text{cm} = 3.375 , \text{cm}^3 \]
So the volume of the cube is 3.375 cm³.
