To find the volume of a cube, you can use the formula:
\[ \text{Volume} = \text{side}^3 \]
Given that the side of the cube is 3 meters, the volume is calculated as follows:
\[ \text{Volume} = 3^3 = 3 \times 3 \times 3 = 27 , \text{cubic meters} \]
So, the volume of the base of the statue is 27 cubic meters.
